Temperatures, Clock Rates & Overclocking
Overclocking & Undervolting
Conventional overclocking through a higher power limit and more aggressive clock rate is a dead-end. Brute force just isn’t the answer. Because Gigabyte had to follow AMD’s guidelines, this implementation is already running at its limit. Sure, you could dial in higher fan speeds to cool things down, creating more noise in the process, but who really wants that? As we explained in AMD RX Vega 64: The Tom’s Hardware Liquid Cooled Edition, even with higher frequencies and brutal power adjustments, it is almost impossible to get Radeon RX Vega running much faster. Instead, undervolting can achieve far better results.
First and foremost, the use of a suitable utility like OverdriveNTool works wonders. As always, though, your results will also depend on the quality of your GPU. We can’t generalize; you’ll have to compare your improvements to ours.
Temperatures & Frequencies
We’re using the GPU temperature value exclusively because that’s what our test sample’s telemetry reports. Of course, the hot-spot temperature is a lot higher. Why? You can read all about in Does Undervolting Improve Radeon RX Vega 64’s Efficiency? On Gigabyte’s Radeon RX Vega 56 Gaming OC 8G, those readings are up to 15°C higher. But they never hit a level that could cause problems.
The following table shows a comparison of start and end values for temperatures and GPU (boost) frequencies:
|Initial Value||Final Value|
|Open Test Bench|
|GPU Clock Rate||1378 MHz||1352 MHz|
|GPU Clock Rate||1378 MHz||1344 MHz|
|Air Temperature in Case||24°C||47°C|
To better illustrate our findings, we plotted temperatures and frequencies during our sample’s 15-minute warm-up phase:
Frequencies in the gaming loop are about 100 MHz higher than what we measured from AMD’s reference card. This average increase of ~10% results in 40W-higher power consumption, or a roughly 18% increase. But the frame rates only go up by 5-7%, which is not a good trade-off at all.
The results of our stress test look similar:
IR Image Analysis For The Board’s Back
To round out this section, we take a look at board temperatures across several different load levels. To keep the test setup as real-world as possible, we drilled a couple of small holes through the backplate at the points relevant to our IR measurements, and then cut out the thermal pads where necessary. Since the diameter of these holes is very small, they have no significant impact on the cooler’s performance.
It’s easy to see that the card is already at its limits during our gaming loop. As long as you operate the Radeon RX Vega 56 Gaming OC 8G vertically on an open test bench, all values seem to be acceptable. But this may change quickly if the card is installed in a closed case instead.
Once we popped Gigabyte’s board into a closed case, we measured up to 6°C-higher temperatures at the voltage converters. It seems as though the fans only respond to GPU temperature, unfortunately. Even a slightly higher rotational speed would have dropped the temperatures by four or five degrees without becoming unpleasantly loud.
The stress test reflects slightly lower power consumption than our gaming benchmark, so the GPU stays a little cooler.
Even in a closed case, temperatures don’t increase by more than a couple of degrees. Still, the 92°C we measured on some of the voltage converters seems quite a bit higher than necessary.

PowerColor Red Devil RX VEGA 56 8GB HBM2 Review
AMD Radeon RX Vega 56 review
Years in development, the new Radeon RX Vega line is finally arriving — AMD’s return to the higher-end of GPU performance after concentrating its efforts more on the mainstream and budget sectors of the market. There’s no shortage of cutting-edge tech here: the Vega processor utilises 12.5 billion transistors on a very large 486mm2 area of silicon, the chip paired with two 4GB stacks of cutting-edge HBM2 memory. It’s a bigger chip than Nvidia’s GTX 1080 Ti and it has more memory bandwidth — however, the top-end RX Vega 64 offers performance more in line with GTX 1080, while the cut-down RX Vega 56 reviewed here is clearly aimed to compete with the GTX 1070. It does this job rather well.
Before we go on, it’s worth stressing that the Vega architecture has a lot of features that may not be utilised much — if at all — today, but could make a big difference in future. For example, the double-speed FP16 support found in PlayStation 4 Pro was pulled ahead of time from the Vega spec sheet (referred to as ‘rapid-packed math’), while AMD has incorporated the most fully featured implementation of DirectX 12 features found in any GPU to date. Meanwhile, the high bandwidth cache controller is an attempt to allow the GPU fast, low latency access to memory beyond the 8GB of onboard RAM.

Elsewhere, the basic layout of Vega looks remarkably similar to the Fiji processor at the heart of the last-gen Fury X, but AMD is keen to point out that every aspect of the GPU has been retooled. There are still 64 compute units and 4096 shaders in the processor — pared back to 56 and 3854 in this cut-down model — but these are ‘new’ compute units with an extended instruction set and a more efficient design. AMD has also sought out faster clocks from the Vega silicon. The last-gen Fiji topped out at 1050MHz, Polaris was coaxed to 1450MHz while Vega is set to hit an impressive 1700MHz — although, again, expect a hit to that in the pared back Vega 56.
Hitting these clocks clearly hasn’t been easy though: even in its reduced state, Vega is undoubtedly power-hungry compared to the competition, as we’ll see later on in this review. That’s borne out by the design of the reference card we’re looking at here: it has two eight-pin power inputs, an even beefier configuration than the Titan Xp, despite its 210W board power rating. By comparison, the GTX 1070 Founders Edition only requires one eight-pin power input, making it easier to integrate with lower-end and medium level power supplies.
The Vega 56 card itself is a robust reference model from a company with a mixed history here — the new offering is an all-metal design, well-built, and features a vapour chamber heatsink (utilised on both Vega 56 and 64), a spec point Nvidia reserves only for GTX 1080, 1080 Ti and current-gen Titan products. External ports are a simple trio of DisplayPort 1.4s along with HDMI 2.0 — a good enough selection, but dual-link DVI should really be included on a card of this class. In operation, the Vega 56 has a temperature limit of 85 Celsius, but typically runs significantly under that. What’s more, there are power saver, balanced and turbo options. We’re reviewing in the default balanced mode, but turbo adds a couple of per cent to performance but increases power consumption.

Before we diving into performance testing, AMD is making a very good point about a specific Radeon feature that proves transformative to gameplay — support for FreeSync. Variable refresh is a genuine game-changer, seeking to eliminate screen-tear and reducing the stutter you see when dropping frames with v-sync engaged. Once you have a VRR screen, it’s difficult to go back to a standard display. Now, of course, Nvidia has its own solution — G-Sync — and while the implementation is generally stronger and more uniform on those screens, they still command a significant price-premium. FreeSync, by contrast, is more likely to be a value-added extra with only a small cost increase. The bottom line is that the price for attaining a smooth variable refresh experience with a GTX 1070/Vega 56 level card is undoubtedly lower with AMD.
We’ll kick off our gaming analysis with a look at 1440p resolution — what we consider to be the best pixels vs performance target for running games at very high or ultra settings on this class of GPU hardware. Whether you’re using the standard 16:9 2560×1440 (as tested here), or else the ultrawide 3440×1440, you’re going to get an excellent experience from all of the cards tested here — high frame-rates and lots of eye-candy. It’s also fertile territory for FreeSync displays, a really good partner for the Vega 56.
For the arrival of RX Vega, we decided to beef up our GPU test suite with a couple of new entrants — Call of Duty: Infinite Warfare has impressed us with its immense level of optimisation and new rendering technologies. It’s also a title that generally runs better on AMD hardware (though Fury X doesn’t hold up so well here, curiously).
Also joining the fray is Ghost Recon Wildlands — the year’s best-selling game (in the UK at least). At ultra settings, this is one of the most GPU-heavy games we’ve tested, and it sucks up VRAM too, meaning that even at 1080p, the old Fury X really struggles here, artificially depressing its frame-rates the higher up the resolution chain you go.
1440p and its ultrawide variant offer the best quality levels and pixel-count for the Vega 56’s capabilities — and it’s ahead of the GTX 1070.

Next up, 4K results — and a question. Is it possible to get a good native ultra HD experience from Vega 56/GTX 1070-class hardware? The established wisdom is that GTX 1080-class hardware is where you start in terms of running top-tier titles but we’ve found that combining the GPU with an adaptive sync screen is a game-changer, as we discovered when gaming on a 1070-powered laptop with a 4K G-Sync display. Tweak settings to remain above 40fps and you can have a great experience. The 30-60fps No Man’s Land — where previously you to put up with v-sync stutter or tearing — is no longer an issue with adaptive sync tech.
In order to can get an idea of scalability between resolutions, our benchmarks remain maxed out here and don’t represent an ideal gaming experience — it’s all about judging relative performance between GPUs with these numbers and in that respect, the Vega 56 extends its lead over GTX 1070 here by a couple of percentage points on most of the titles tested. Even with the depth of field issue, AC Unity draws level and the only area of parity remains the puzzling performance of Crysis 3 on the new hardware. Factoring out those outliers, the overall lead is 12.8 per cent in favour of the AMD card.
Elsewhere, there are other results that once again show the stock Vega 56 operating at a kind of mid-point between GTX 1070 and GTX 1080 performance — Ashes of the Singularity seems to have regained its lead on AMD hardware after some driver revision work by Nvidia, but The Division, Far Cry Primal, Ghost Recon Wildlands and COD Infinite Warfare represent half of our tested games where the Vega 56 posts significant results that sit midway between 1070 and 1080 performance.
The Hitman result is another outlier — Vega 56 is still faster than GTX 1070, but the average frame-rate result is impacted a touch by occasional stutter, seen across all resolutions. It hits hardest on scene changes (but manifests occasionally elsewhere too) and is unlikely to affect gameplay.
You can game at 4K effectively with this class of card, but judicious settings tweaks are required and an adaptive sync display is a game-changer for the experience.

If you want the highest frame-rates — but also the most variable gameplay experience — 1080p is the place to be. There are some remarkably high frame-rates here, but the averages don’t tell the story of the often janky experience you get here as you careen between CPU, GPU and even storage bottlenecks. It’s probably best seen here on the COD Infinite Warfare test, where 1080 and 1080 Ti hit the limit, with Vega 56 getting very close — the average grabbed down a touch by stutter you don’t seem to get on Nvidia cards.
We use benchmarks to get an idea of relative performance under identical workloads, but it’s fair to say that we’re hitting so many different limits here that’s it’s not hugely instructional in terms of getting value from your GPU. However, there are a couple of takeaways — principally in how competitive the Vega 56 is overall here at lower resolutions compared to the Fury X, GTX 1070’s prior competitor in this space.
Looking back at our Fury X review, we saw a GPU competitive with Nvidia at 4K resolutions, but with gradually worsening relative performance the lower down the resolution chain you went — we even saw it on the pixel-rich ultra-wide 1440p tests we carried out. The driver improved over time and performance improved but even here you can see that Fury X performance worse here against the 1070 than it is at higher pixel-counts. With Vega, the fact is that AMD is still faster than GTX 1070, by and large, or at least maintaining parity. Whether it’s down to the hardware design or driver optimisations is difficult to say but the numbers speak for themselves.
Whether you’re gaming with Nvidia or AMD though, it’s difficult to come to any conclusion other than that you’re leaving a lot of GPU power on the table by deploying such a powerful GPU on such a low resolution overall — RX 570, RX 580 and GTX 1060 offer a far more consistent experience overall for full HD gamers.
1080p offers the highest frame-rates but also the most inconsistent experience. You don’t get the best out of any of these GPUs at this resolution.
|1920×1080 (1080p)||RX Vega 56||R9 Fury X||GTX 1070||GTX 1080||GTX 1080 Ti|

If the new AMD architecture has a weakness, it is power consumption, where the Vega 56 posted a 25 per cent increase in power consumption in our Crysis 3 stress test, where the card is handing in exactly the same performance as the GTX 1070. However, we’re clearly looking at a substantial improvement in terms of both efficiency and performance compared to the old Fury X.
You’ll note that a fully maxed out overclock sees power consumption go through the roof. Here we’re running the Vega 56 card with its power slider maxed at +50 per cent, core frequency bumped by 11 per cent and with HBM2 RAM pushed to 950MHz, putting the card on par with the Vega 64’s prodigious 484GB/s of memory bandwidth. Generally, this overclock provides anything between a seven per cent to 14 per cent performance uplift, but the fans need be adjusted upwards to keep temperatures in check. With that in mind, pushing Vega 56 hard is a task probably better suited to third party cards that are coming in Q4 this year.
As expected, those games where performance sits at a mid-point between GTX 1070 and 1080 performance can match the higher end card’s stock frame-rates, or get to within margin of error. The Division overclocks to 72.5fps vs the 71.3fps on GTX 1080, for example. Hitman and Ashes of the Singularity match GTX 1080, as does Far Cry Primal. We tested overclocking at 1440p resolution, so results may be even more favourable at 4K.
Another route forward is simply to overclock the HBM2 memory to 950MHz and leave everything else alone. This requires little extra power (we gave it an extra five per cent but it may not even require that), it won’t impact thermal performance that much (if at all) and we noted that in titles like Hitman and The Witcher 3, overclocking memory alone got you approximately half of the performance increase of the maxed OC results. It’s worth experimenting with as it is essentially free performance with no downsides — the best kind of overclocking, in our opinion.
This scene from Crysis 3 is easily repeatable and incurs a heavy, sustained load on the GPU — good for testing overclock stability and for measuring power draw. We retain our Core i7 6700K here, but disable its overclock.

If you’re looking for an alternative to the GTX 1070, the bottom line is that you’re generally getting around 10 to 12 per cent of additional performance with the Vega 56, at the cost of some efficiency. It’s also interesting to note just how consistently the card out-performs its competitor — only oddments and bugs along with a strange turnout from Crysis 3 stop it from dominating across the board, even on titles that traditionally favour Nvidia hardware, such as Rise of the Tomb Raider.
Assuming the recommended US pricing holds up — and that the Ethereum mining boom doesn’t jack up the costs horrendously — the value on offer here is very good overall, especially if you own (or are considering) a 1440p or 4K FreeSync display, which pairs nicely with this product and constitutes one of the most profound gaming upgrades money can buy. At the time of writing, UK pricing is not available, but if it costs too much more than GTX 1070, that would take the shine off an impressive product.
How Vega 56 compares with its more expensive counterparts is something we are still in the process of testing. However, we’ve run some initial tests on the top-end liquid-cooled version of the Vega 64 (full review incoming — we’ve had only five days with these products, which is not ideal) and first impressions suggest that the Vega 56 offers around 85 per cent of the performance of the fully maxed Vega experience, and that gap may close up a little against the air-cooled version.
It’s early days with testing there, but it may well be the case that the Vega 56 isn’t just a great value contender against GTX 1070, but also its higher-end siblings too. We’ll try to get some further numbers to you as soon as possible, but it seems clear that the Vega 56 is AMD’s value play, where it performs very well indeed. Aside from the 2x eight-pin power input requirement and the lack of a DVI port for legacy display support, it’s difficult to find much fault with what AMD has delivered here — there’s strong performance out of the box, various routes forward with overclocking that deliver tangible results, and the quality of the reference card (the only Vega option for a while) also represents a big improvement over prior AMD efforts. It’s been a long time since AMD has challenged Nvidia at the higher-end, but Vega 56 hits the sweet spot — it’s a superb performer overall.

Inside the card, we can see that the card uses a full length PCB and houses the Vega 10 GPU on its interposer along with the HBM2 VRAM. There are two stacks of HBM2 memory that are 4-Hi each and incorporate up to 8 GB of HBM2 VRAM. The card has power phases running around the GPU. The card uses a plastic base plate to provide extra support to the PCB and heat dissipation. There is a single blower fan that pushes air towards a large isothermic vapor chamber and out of the assembly and through the exhaust vents on the I/O which also feature a HDMI and triple DisplayPort connectors.
In terms of clock speeds, both reference and limited edition (air cooled) models will be shipping with out-of-box frequencies of 1247 MHz (base clock) and 1546 MHz (boost clock). The TDPs has been configured at 295W for the air cooled models and power will be provided through dual 8 pin connectors.
AMD Radeon RX Vega 64 Liquid Edition — Faster Clocked Vega Starting at $599 US, 350W TDP
The third model is the Radeon RX Vega 64 Liquid Edition which as the name suggest will feature liquid cooling. The Radeon RX Vega 64 liquid cooled model looks very similar to the Radeon Vega Frontier Edition Liquid which has already been launched and will come with higher / stable clock speeds compared to the air cooled variants and better cooling potential.
Both cards look premium and nicely designed with the whole brushed silver texturing. The Radeon RX Vega 64 graphics cards are powered by dual 8 pin power connectors and will require beefy power supply units to keep them fed under heavy gaming loads. The TDP for the Liquid cooled models will be configured at 350W.

AMD Radeon RX Vega 64 Performance Numbers — Just on par With a Reference GTX 1080
AMD is using the flagship Radeon RX Vega 64 Liquid cooled models in most of the benchmarks and this variant has the highest clock speeds of all. In performance tests, AMD used a reference GTX 1080 against their RX Vega 64 Liquid edition and most of the results were on par with the GeForce solution. The difference here is that AMD is calling RX Vega 64 as the smoother option for the same price.
2 of 9
In test results, the AMD Radeon RX Vega 64 achieved 53 FPS (Min) and 76 FPS (Max) in a range of games at 4K. The GeForce GTX 1080 scored a higher Max frame rate of 78 FPS but was slower in terms of minimum frame rate with 45 FPS. AMD used their flagship liquid cooled model that costs $599 US against the GTX 1080 which costs $499 US. I personally believe that AIB custom models of the GTX 1080 will be able to outpace the RX Vega 64 Liquid in such tests.
AMD Radeon RX Vega 56 Air Cooled Reference Model — The Cut Down Vega For $399 US
AMD will also be shipping the Radeon RX Vega 56 which is based on the cut down Vega 10 die. The card will be available in reference only variants at launch and feature the same blower styled cooler as the Radeon RX Vega 64 reference model. The graphics card will feature 3584 cores that will be clocked at 1156 MHz base and 1471 MHz boost. The chip will feature a total compute horse power of 10.5 TFLOPs (FP32) and will feature a TDP of 210W which will be provided through an 8 and 6 pin power connector configuration.
The Radeon RX Vega 56 will also feature 8 GB of HBM2 VRAM which will deliver a rated bandwidth of 410 GB/s along a 2048-bit bus interface. In terms of pricing, the model will hit retail for $399 US however pricing has not been confirmed yet.
AMD Radeon RX Vega Nano Spotted — Teased by Chris Hook at Capsaicin Siggraph 2017
AMD has also teased their latest Nano, the Radeon RX Vega Nano at Capsaicin Siggraph. The event is supposed to go live in a bit so we will definitely hear more details soon. As for the card, it will feature the same Vega 10 GPU although we aren’t sure if it will be based on the Vega 64 or Vega 56 SKU. The card however is as small and similar in design as the previous Radeon R9 Nano graphics card which was a hit among the SFF community.

Powercolor red devil vega 56 8gb review and Tests 
In this mining review, we will look at the characteristics of the PowerColor red devil vega 56 8gb video card from AMD and its mining performance.
The card has 2 power phases 2×8 Pin connectors. The card consumes 210 watts out of the box, but with maximum overclocking, you can reach a consumption of 300 watts. With maximum overclocking using MSI Afterburner, the card produces 1870 H/s on CryptoNightV7 and 1620 Kh/s on NeoScrypt.
Specifications Specifications Powercolor red devil vega 56 8gb Video memory HBM2 8GB Processor frequency Overclocking frequency: 1526MHz
Out of the box — 1308MHz
Memory frequency 1600 MHz Power connectors 1x-8Pin, 1x-8Pin Dimensions 316 mm x 150 mm x 55 mm
for this product!
How much can you earn? Also not bad, but already a little worse than the previous ones, coins are mined on the Ethash and X16R algorithms.
Next come the algorithms that bring the least profit: «Equihash», «Lyra2REv2» and others.
It should be noted right away that although many people are used to the fact that AMD cards mine Ethash (Ethereum) perfectly, vega 56 still mines coins of other algorithms perfectly.
Consider examples of mining on a PowerColor red devil vega 56 8gb video card (tests were carried out on 06/09/2018).
For example, on the «CryptoNightV7» algorithm from one PowerColor red devil vega 56 8gb video card per day:
- Total coins – 0.0154 xmr.
- USD equivalent of mined coins – $2.52
Also consider the same profitable algorithm — NeoScrypt, when mining with one PowerColor red devil vega video card in one day:
- Total coins — 0.4142Gbx.
- USD equivalent of mined coins – $2.18
Both algorithms are great for mining and the profit from mining coins on these algorithms is almost the same. However, the difficulties are constantly changing and from time to time it is beneficial to mine different coins of these algorithms.
Next come the algorithms that already bring much less money.
Consider the tests of mining on the Ethash algorithm from one PowerColor red devil vega 56 video card in one day:
- Total coins — 0.0029ETH.
- USD equivalent of mined coins – $1.76
Let’s consider tests of another less profitable algorithm — Equihash.
By mining coins on the Equihash algorithm using a PowerColor red devil vega 56 video card, in one day you will receive:
- Total coins — 0.0048ZEC.
- USD equivalent of mined coins – $1.30
Other algorithms will bring about the same profit as Equihash, and some even less than $1 per day.
It is also worth noting that if you really want to mine, for example, Zec coins, then it is best to do this with the help of “pseudo mining”. That is, to mine coins of profitable algorithms (for example, in this case, the Monero coin), and then sell and buy the received coins with the proceeds of Zec.
It turns out the following:
- Monero mining will bring ~ $ 2.52 per day.
- Zec mining will bring ~$1.30 per day.
It turns out that if you mine Monero, you will receive $1.22 more, which means you will receive more Zec coins. The same can be said about Ethereum and other coins of less profitable algorithms.
Ethereum mining, with flashed BIOS:
Mining NeoScrypt with overclocking:
In mining, the video card produces the following hashrate:
Hashrate Algorithm MH/s (stock/overclock) Equihash 415/440(H/s) Ethash 30/41 (MH/s) NeoScrypt 1580/1630 (Kh/s) CryptoNightV7 1810/1860(H/s) Skunkhash 34/36. 2 (MH/s) NIST5 38.7/40.4(MH/s) Groestl 36.7/38(MH/s) Lyra2REv2 12900/13100 (Kh/s) PHI1612 0/0(MH/s) TimeTravel10 13.1/14.3(Mh/s) Xevan 0/0(MH/s) X16R 10.2/11.1
Memory and overclocking
The card is equipped with 8 gigabytes of memory, more often Samsung and Elpida, less often Micron.
Core clock ~ + 950 — great for perfect work without crashing.
Memory clock ~ +1300 — this is an ideal overclocking indicator, at which the card works stably (does not issue rejections) and the system does not reboot (does not crash)
With this overclocking, the card produces:
- NeoScrypt — 1600-1620 Kh / s
- CryptoNightV7 — 1862 — 1870 H/s
Power consumption and downvolting
Out of the box, the card consumes 210 watts, of which 75 watts go through the PCI-e line (riser), and the rest through the 2×8 PIN power connectors. At maximum overclocking, consumption reaches 300 watts.
Recommended power supply for a 6-card farm with a connected system ~ 2000 Watts.
When downvolted to 260 watts, the card loses only 70-100 Kh/s on the NeoScrypt algorithm.
What is downvolting? This is a means by which there is an underestimation of the energy consumed by the video card.
What coins can be mined? Coins on these algorithms bring the most profit per day. Other algorithms (such as Ethash) are slightly less profitable, which means they bring less money per day. Below are the coins that can be mined.
Mined coins Algorithms Coins NeoScrypt Crowdcoin, Dinero, Feathercoin, GoByte, Halcyon, Innova, Vivo, Trezarcoin, Orbitcoin, Phoenixcoin CryptoNightV7 Monero, Electroneum Ethash Ethereum, Ethereum Classic, Ellaism, Metaverse, Expanse, Krypton, Ubiq, Soilcoin, Shift, Pirl, Musicoin Equihash Zclassic, Hush, Zcash, Zencash, BitcoinGold, Komodo, BitcoinZ, Bitcoin Interest, Bitcoin Private, BitcoinZ, Zero TimeTravel10 Bitcore Lyra2REv2 Monacoin, Galactrum, Rupee, Straks, Vertcoin, Verge X16R Ravencoin
Dual is the extraction (mining) of two different coins at once.
The main thing to understand is that you cannot mine 2 coins of the same algorithm. For example, you will not be able to mine on the Ethash Ethereum and Ethereum Classic algorithm (or other coins of this algorithm).
But you can mine coins in this combination of algorithms:
- Ethash + Blake (2s)
- Ethash + Equihash
- Ethash + Blake (14r)
- Ethash + keccak
With the release of the asic for the Blake algorithm (14r), mining (by GPU, that is, on video cards) such coins as Decred (DCR) is almost impossible due to unprofitability.
Pros and cons of dual mining on powercolor:
Let’s say you mine Ethereum (ETH). You can connect a second coin on a different algorithm, for example, + Verge-Blake (2s). You can mine the second coin without losing power on Ethereum. In this case, the best option is to give power to Verge-Blake (2s) in the amount of 10-20%.
You get the following (with blockchain driver, overclocking and firmware BIOS):
- Ethereum — 40MH/s
- Verge ~ 320MH/s.
Plus dual in this case:
You do not lose the mining power of the main coin
You get an additional coin weather and in a poorly cooled room, it is better not to run dual mining, as the cards can overheat a lot!
Comparison of PowerColor red devil vega 56 8 gb with analog video card line
Consider the difference between other brands that make Vega 56, and the difference between vega 56 and vega 64.
The difference between the brands is almost imperceptible.
For example, Asus also does an excellent job of cooling. PowerColor parts are reliable and high quality, like Asus and Sapphire.
The difference will be between dual-cooler models, which in turn cool the card worse.
Also red devil, from the factory it has slightly less overclocking than many of its competitors, but this is not a problem, since the card can always be overclocked manually, through certain programs (for example, Msi Afterburner).
The difference between Vega 64 and Vega 56
In mining, this difference is noticeable. For example, Vega 64 on NeoScrypt produces ~2050 Kh/s, while Vega 56 produces ~1620 Kh/s. This is a noticeable difference.
Vega frequency 64 ~ 1607 MHz, when 56 ~ 1526 MHz.
Therefore, if the choice is about assembling a farm on Vega, then it is better to take 64, since it is more powerful, which means it will bring more money. Also, with ever-increasing complexity, it will be relevant longer than 56.
Comparison of PowerColor red devil vega 56 8gb with PowerColor RX VEGA 56 Red Dragon 8GB
The difference is almost minimal. Both cards have 3 coolers and an excellent cooling system, except that the Dragon will be 2-3 degrees colder.
But at the same time, Dragon is less overclocked at the factory — 1478MHz. It is difficult to call this a strong difference, since the cards have the same chips, and it will not be difficult to overclock the card yourself. But it is worth noting that cards overclocked from the factory can overclock less in Afterburner, since they have already been overclocked, but at the same time they often work a little more stable.
As you can see, the difference between these two models is almost imperceptible, so when choosing between these cards, be guided by the price and take the one that is cheaper.
Which drivers to use
Install the Blockchain driver from AMD, it is designed specifically for mining.
Temperatures and internals
- Weight — 1414
- Length — 31 cm.
- Noise — 40 dB
The card has 3 coolers, which, according to the manufacturer, reliably protect the card from dust. However, in mining, after 2 months, the card is covered with a small layer of dust.
The map also has a tight backplate.
When working in mining, the card does not exceed 66 degrees Celsius at 100% cooler speed. In a rig of 6 cards, with a distance of 10 cm from each other, the temperature is not higher than 70 degrees.
Without disassembling the card, we can already conclude that this is almost a complete copy of the reference board.
Internal cooling system
Removing the backplate, we immediately see the GPU, which is very heavily smeared with thermal paste.
Next, we observe a radiator and thermotubes. The radiator is copper, with a nickel-plated block, which is lubricated with thermal paste. It is adjacent to the GPU and looks very massive.
5 thick copper heat pipes run through the entire grille.
Please note that the memory and VRM are thermally sealed for additional cooling. This is great for mining, as algorithms that are well mined by this card are hotter than others. It is also worth noting that recently there are few manufacturers who install additional cooling — thermal stickers for memory and VRM.
Having freed the board from the cooler and backplate, we can say for sure that the video card has a 98% reference design. That is, as we said earlier, PowerColor red devil vega 56 is a reference board.
The back of the GPU has many ceramic capacitors.
Map measurement with thermal imager
Thermal images show the following result:
Measuring point Celsius) M1 64.9 M2 58.8 M3 55.4 M4 62.7 M5 66. 8 M6 62.9 M7 70
So the graphics card reaches ~65 degrees on M1 — that’s the GPU area. Also the VRM (graphics card power area) doesn’t seem too warm.
Measuring point Celsius) M1 68 M2 63.3 M3 32.4 M4 44.9 M5 43.7 M6 36. 5
When we mount the thermal chamber on the side, we can see that the coolers work very well, blowing warm air out.
Measuring point Celsius) M1 73 M2 59.9 M3 33.4
The GPU and VRM area heat up to about 60 degrees — this is ideal and is considered a good operating temperature.
Negative qualities of the card and output
At home (in the apartment), the video card feels great. The only downside is that at speeds above 80% the cooler is very noisy. The noise from a farm of 6 such cards is equal to a working vacuum cleaner. Plus, due to the intense heat from the cards, it is advisable to install a fan to dissipate heat, which will also add noise.
You should also pay attention to the coolers themselves: despite the fact that they supposedly protect against dust, when mining, that is, working 24/7 in the farm, the cards are covered with dust after 2 months. Six months later, there were cases when it became difficult for the coolers to spin. Therefore, try to blow dust off the cards every 2-3 months.
PowerColor red devil vega 56 8 GB is a great card for mining. It keeps an excellent temperature: in a rig of 6 cards, it does not exceed 70 degrees.
However, it is worth noting that additional cooling will not damage the farm of such cards, since the card consumes up to 300 watts during overclocking, which means it generates a lot of heat, which must be dissipated as soon as possible.
Due to the large number of thermal stickers, the card can better withstand hot algorithms, as well as algorithms where you need to overclock the memory.
- Low temperature maintenance
- Great for mining coins on NeoScrypt and CryptoNightV7 algorithms

Object of study : AMD Radeon RX Vega 56 8 GB 2048-bit HBM2 3D graphics accelerator (video card) . In the same year it was renamed to ATI Technologies. Headquartered in Markham, Toronto. C 19For 87 years, the company has concentrated on the production of graphic solutions for PCs. Since 2000, Radeon has become the main brand of ATI graphics solutions, under which GPUs are produced for both desktop PCs and laptops. In 2006, ATI Technologies was acquired by AMD, which formed the AMD Graphics Products Group (AMD GPG). Since 2010, AMD has abandoned the ATI brand, leaving only Radeon. AMD is headquartered in Sunnyvale, California, while AMD GPG remains headquartered at AMD’s former office in Markham, Canada. There is no production. The total number of AMD GPG employees (including regional offices) is about 2,000 people.
Part 1: Theory and Architecture
Not so long ago we released a large baseline review of the AMD Radeon RX Vega 64, AMD’s new flagship product, and today it’s time to get acquainted with a less expensive model, presented simultaneously with the top-end Radeon RX Vega 56. Although the announcement of several powerful solutions of the company at once, based on the Vega 10 graphics chip, took place on the same day, the younger video card hit the market and fell into our hands a little later.
Accordingly, in this article we will not dwell on the theoretical part and architectural changes, which you can find in the review of the older model. In short, the Vega architecture was the most significant change to AMD’s GPUs since the first GCN-based solutions. The new architecture features better power efficiency, scalability and flexibility, supports a special cache for working with large amounts of data, and has numerous microarchitectural improvements.
The main feature of the new Vega graphics architecture is the use of a new “scalable memory architecture”, which is based on very fast second generation HBM memory, installed on a single package with a GPU die, and has a wide data bus. Moreover, it can work in two modes: normal, when it is just local video memory, and also as a high-performance cache memory — High Bandwidth Cache, which speeds up access to data stored outside the local video memory. All this is described in detail in the article on Vega 64, and we turn to the description of a video card using a stripped-down Vega 10 chip.
At the announcement, AMD introduced several models of video cards of the RX Vega family based on the next generation graphics architecture. These models differ from each other in characteristics and performance, as well as in the cooling system and price. Three models have been announced: the Radeon RX Vega 64 Liquid Cooled Edition, the regular RX Vega 64 we’ve already reviewed, and the less powerful RX Vega 56 based on a variant of the Vega 10 GPU that deactivated some of the execution units.
Since the video cards of the Radeon RX Vega family are based on the Vega 10 graphics processor, which has an improved GCN architecture, which is similar in many details to previous AMD solutions, before reading the theoretical part of the article, it will be useful to familiarize yourself with our previous materials on past video cards companies based on the GCN architecture:

The name of the video card in question corresponds to the new naming system for the line, which has its own name — Vega. The number after the family name means the number of active execution units of the GCN architecture in the GPU — 64 for the full version or 56 for the stripped-down version of the Vega 10 chip. The initial letters RX have remained, now they no longer mean anything special and are included in the names of all modern AMD video cards.
The Vega family model reviewed today updates the company’s current lineup, complementing the Polaris family at the top and sitting among AMD video cards just below the Vega 64. and water-cooled, which have a higher price:
The range in the price of solutions in the line ranges from $399 for the RX Vega 56 to $699 for the top water-cooled video card. And in the case of Packs, we are talking not only about the video card, but the whole pack, which costs an extra hundred dollars. For an additional $100, AMD added the ability to purchase a modern monitor, processor, and motherboard at a significant discount. In addition, the set also offers free games.
Specifically, the company’s offer includes $200 off the Samsung CF791 34″ ultra-wide modern FreeSync monitor, and $100 off select Ryzen 7 processors bundled with X370 motherboards—that’s one thing. gives a savings of $300, and they also offer games in a bundle, which will depend on the region. The relevance and profitability of this offer depends on many circumstances, so it’s easier to evaluate «bare» video cards.
The reference version of the Radeon RX Vega 56 without any additions is offered at a suggested price of $399, and this price could be called attractive, since the new product has to compete with a competitor model such as the GeForce GTX 1070, which is clearly slower than the Vega 56 (we’ll find out how specific in the next sections of our article with synthetic and gaming tests). But alas, the shortage of video cards of the Vega family and the rather high cost did not allow the retail price to reach the recommended level, and this must be taken into account when assessing the market prospects of the new AMD product.
Like the top Vega 64, the stripped-down Vega 56 is available exclusively in versions with 8 GB of HBM2 memory, since the memory bus width has not changed. We have already said that installing exactly 8 GB of memory is a justified practical solution, because 4 GB for a top-end card will be too small, and it makes no sense to install 16 GB — given the very high cost of HBM2 memory and the sufficiency of 8 GB in most modern games . So 8 GB can be considered the «golden mean», especially for the not the most expensive option on Vega 10. Moreover, the video memory on the solutions of the line can be expanded using system memory in case of emergency.
Since the Vega 56 reference board is not very different from the older version, it also uses two 8-pin connectors for additional power. The typical power consumption for the Radeon RX Vega 56 model based on the reduced number of execution units of the Vega 10 GPU is set at 210 W, which is noticeably lower than the 295 W for the Vega 64. And this is very good, because the consumption of the Radeon RX Vega 64 is quite high compared to competing solutions.
The AMD solution under consideration is based on the Vega 10 architecture GPU, which is manufactured using the 14 nm FinFET LPP manufacturing process and contains 12.5 billion transistors, and the Infinity Fabric bus known from the company’s processors is used for internal communications. The Vega 10 GPU belongs to the Graphics Core Next architecture, the base unit of which is the Compute Unit (CU) from which all AMD GPUs are assembled.
The CU compute unit (named NCU in the case of this chip) has a dedicated local data store for data exchange or local register stack expansion, as well as a read/write L1 cache and a full texture pipeline with fetch and filter units, it is divided into subsections, each of which works on its own command flow. Each of these blocks deals with planning and distribution of work independently.
A stripped-down modification of the Vega 10 GPU contains four engines for asynchronous command execution and a geometry engine, but out of 64 physically available new-generation Compute Units, only 56 are active.6 physically available in the GPU) stream processors, 224 (out of 256) texture units. But the number of ROP blocks remained unchanged — there are 64 of them, as in the top model. Let’s take a look at the circuit of a stripped-down GPU (a larger version of the illustration is available by clicking on the image): energy efficiency. The Radeon RX Vega 56 in question is capable of delivering 10.5 teraflops of single-precision performance and 21 teraflops of 16-bit half-precision, which was first introduced in Vega.
The Vega GPU uses AMD’s standard Infinity Fabric internal bus, which has low latency and is designed to connect different processor units to each other — for example, the main graphics core with other logical units, such as memory controllers, PCI Express controller, display engine, video processing engine.
The new graphics processor uses HBM2 memory running on a 2048-bit bus at 800 MHz, giving a pretty hefty 410 GB/s bandwidth. The saddest limitation of HBM1 memory, known from Fiji GPUs (Fury series video cards), has also been eliminated — the maximum limit of 4 GB of video memory. In the case of HBM2 memory, up to 32 GB is theoretically possible, but AMD decided to put 8 GB of HBM2 memory on game chips, since its cost is very high.
If there is not enough video memory, then the HBM2 memory in Vega can be used as the last level cache for system memory and data storage devices. According to AMD, the high-performance cache and its controller allow for flat virtual addressing of up to 512 terabytes of data on different media, and its operation is completely transparent to user applications. This approach allows you to use more data than can fit in the video memory. To solve these problems, a new high-performance cache memory controller, the High Bandwidth Cache Controller (HBCC), was introduced into the Vega GPU, which we wrote about in the Vega 64 review.
Among other important differences between Vega and earlier AMD graphics architectures, we note the new programmable geometry engines of the new generation, which allow to increase the speed of geometry processing several times, improved NCUs with the ability to perform 16-bit calculations at a double rate, new pixel engines, using Draw Stream Binning Rasterizer (DSBR) tile rasterization, reducing the number of video memory accesses and increasing performance and power efficiency, also supporting most DirectX 12 features with Feature Level 12_1 and much more.
And beyond that, the Vega 10 GPU offers state-of-the-art support for all the latest display output standards, surpassing previous Polaris family solutions. We also note that the Vega 10 GPU includes the most advanced engines for encoding and decoding video data. Read more about all the technologies and capabilities of the GPU in the basic review of the AMD Radeon RX Vega 64 graphics card.
The Vega architecture provides a significant performance improvement over the company’s previous GPUs. The combination of architectural improvements and higher GPU frequencies allows new graphics cards to significantly outperform previous generation GPUs of similar positioning. Progress is noticeable in almost all respects, the GPU clock frequency has especially clearly increased due to the use of a more advanced technical process — it has grown by one and a half times, which affected most theoretical figures, and the speed of FP16 calculations has increased even more — thanks to Rapid Packed Math technology.
In Vega 10, the volumes of on-chip caches increased, and the amount of video memory was doubled, but the memory bandwidth remained approximately at the same level as that of Fiji. 410 GB / s is quite a lot, but this value can be achieved using GDDR5X memory, and even the fastest GDDR5 memory lags behind, but not so much that it affects overall performance. But it costs much less in production and development, which would have a positive impact on market availability and retail prices. But several years ago, AMD made a bet on the use of HBM in their top-end solutions, and this has its advantages — see High Bandwidth Cache.
The Radeon RX Vega 56 graphics card is the second solution in the new family based on the Vega GPU, manufactured using the 14 nm FinFET LPP process we are reviewing. AMD’s new GPU features enhanced functionality and numerous architectural optimizations to improve performance and power efficiency across the family. We’ll return to the issue of performance when reviewing the results of our tests in the next two parts of the material.
According to preliminary estimates and tests, the Radeon RX Vega 56 looks very good, often outperforming its competitor in the face of the GeForce GTX 1070, especially given the lower recommended price. But here it should be taken into account that the Nvidia video card has been on the market for a very long time and its prices have settled down for a long time, in contrast to the new product from AMD, which is still sold in insufficient volumes and clearly at inflated prices, which does not allow making unambiguous conclusions about its competitiveness.
