What’s The Best 8-Core Processor?
We’re still waiting on AMD’s
final Socket AMD 4 piece to the puzzle — the Ryzen 9 3950X, which was recently delayed till November, but today I’m looking at the Ryzen 7 3800X, which is AMD’s fastest 8-core, 16-thread CPU, sitting above the Ryzen 7 3700X and below the 12-core 24-thread Ryzen 9 3900X. There are two Intel
CPUs that are relevant here in terms of a direct comparison. Firstly there’s the Core i7-9700K, which also has eight cores and costs about the same at $380 versus $390 for the AMD CPU.
However, it only has 8 threads and lacks hyper-threading, plus it’s not the fastest Intel 8-core CPU out there.
Antony Leather
That honor goes to the Core i9-9900K, which I’ve chosen as the direct comparison in the graphs for the simple reason we’re looking for the best 8-core CPU here and the Ryzen 7 3800X and Core i9-9900K represent AMD and Intel’s current 8-core flagships. That said, the Core i9-9900K costs around $70 more (a little less if you opt for the 9900KF which lacks onboard graphics) than the Ryzen 7 3800X so really, this is a three-way fight between the similarly-priced AMD CPU and the Core i7-9700K, and the AMD CPU and the Core i9-9900K, which has the same number of cores and threads. I’ve highlighted results for all three plus a bunch of other CPUs in the graphs too.
| Cores/Threads | Base/Boost Freq | Total Cache | TDP (Watts) | Included cooler | SEP (USD) | Availability | |
|---|---|---|---|---|---|---|---|
| Ryzen 9 3950X | 16/32 | 3. 5GHz/4.7GHz |
72MB | 105W | Wraith Prism RGB | $749 | September |
| Ryzen 9 3900X | 12/24 | 3.8GHz/4.6GHz | 70MB | 105W | Wraith Prism RGB | $499 | July 7, 2019 |
| Ryzen 7 3800X | 8/16 | 3.9GHz/4.5GHz | 36MB | 105W | Wraith Prism RGB | $399 | July 7, 2019 |
| Ryzen 7 3700X | 8/16 | 3.6GHz/4.4GHz | 36MB | 65W | Wraith Prism RGB | $329 | July 7, 2019 |
| Ryzen 5 3600X | 6/12 | 3.8GHz/4.4GHz | 35MB | 95W | Wraith Spire | $249 | July 7, 2019 |
| Ryzen 5 3600 | 6/12 | 3.6GHz/4.2GHz | 35MB | 65W | Wraith Stealth | $199 | July 7, 2019 |
Specifications-wise the Ryzen 7 3800X is identical to the Ryzen 7 3700X under the hood with 8 cores and 16 threads plus 36MB total cache.
However, the latter has a TDP of 65W versus 105W for the Ryzen 7 3800X due to the fact it has lower boost frequencies, dropping 300MHz on the base frequency, which amounted to a 200MHz lower all-core boost of 4GHz compared to 4.2GHz for the Ryzen 7 3800X, while the latter has a 100MHz higher peak boost frequency too. However, as I mentioned in my Ryzen 7 3700X review, it costs significantly less in the U.S at least, yet was overclockable to 4.3GHz across all cores — just 100MHz short of what you’d see in a single core at stock speed. The Ryzen 7 3800X has its work cut out if it’s to justify its higher price tag.
Test system
Antony Leather
I’ve rebuilt my test systems so they use cutting-edge components and also fully up to date versions of Windows 10 with the May 1903 update along with all the various security patches — both from motherboard manufacturers and Microsoft as these are known to have impacted on performance making any data obtained prior to these updates incomparable and unrepresentative.
I should also point out that I’ve used 3466MHz memory with all my systems now as this worked with older AMD CPUs as well as new ones, painting them in their best light, especially given memory prices are so low at the moment. You may see slightly better performance using faster memory, but you’ll be unlikely to get that working on 1st Gen Ryzen CPUs.
Overclocking: I managed to overclock the Ryzen 7 3800X to 4.4GHz with a vcore of 1.425V — the maximum I use with AMD CPUs and always suggest you aim to lower that for an every-day overclock if you do it yourself. Other CPU overclocks include: Ryzen 5 3600: 4.25GHz, Ryzen 5 3600X: 4.25GHz, AMD Ryzen 9 3900X: 4.3GHz, AMD Ryzen 7 3700X: 4.3GHz, AMD Ryzen 7 1800X: 4GHz, AMD Ryzen 7 2700X: 4.2GHz, AMD Threadripper 2920X: 4.2GHz, Intel Core i9-9900K: 5GHz, Intel Core i7-9700K: 5.1GHz, Intel Core i5-9600K: 5GHz, Intel Core i7-8700K: 5GHz.

Gaming Benchmarks
Shadow of the Tomb Raider
I use the built-in benchmark results here as it provides an in-depth look at performance, but it does use a 95th percentile rather than the 99th percentile I use in my other games’ manual tests. The difference is usually negligible, but bear that in mind. The Intel CPUs both have a lead here, with the AMD 8 and 12 core CPUs bunched together at around 105fps 95th percentile minim frame rate and 129fps average frame rate, with all three within the margin of error, which can be a few frames per second in this game, but it’s fairly clear that Intel’s 8-core CPUs have big leads with a relatively powerful graphics card and the most popular gaming resolution — 1080p, which does lean more on the CPU.
Antony Leather
Far Cry 5
Far Cry 5 seems to love CPUs that have the same number of cores as threads, so it wasn’t a surprise to see the Core i7-9700K and Core i5-9600K do well here. However, the next fastest CPU was the Ryzen 7 3800X when overclocked and it was quicker than the Core i9-9900K too.
Antony Leather
Dota 2
Dota 2 is an easy game to run but is a good example of what happens at high frame rates that are likely to appeal to those with high refresh rate monitors. Intel usually does well here and it was certainly the case in Dota 2, although you’d be hard-pressed to see the difference between the 103fps and 112fps 99th percentiles between the Ryzen 7 3800X and Core i7-9700K, but it’s a win for Intel nonetheless. As you’ll see in various other benchmarks, the overclocked result for the Ryzen 7 3800X is lower than the stock speed result, for the simple reason the frequency is lower than the peak stock boost speed.
Antony Leather
Content creation benchmarks
Adobe Premiere Pro
In games AMD not far off at all and faster in some titles and that’s at 1080p which will always show bigger differences. However, as usual, things don’t just reverse in content creation, but take a massive swing in favor of AMD. Premiere Pro saw the Ryzen 7 3800X perform the same as the far more expensive Core i9-9900K and totally out class the Core i7-9700K.
Antony Leather
Cinebench R20
A third place result in Cinebench’s single-threaded test is excellent for AMD, although once overclocked, the Core i7-9700K was quicker thanks to a massive 5.1GHz frequency, but if you’re not overclocking the AMD CPU is once again a match for Intel’s more expensive flagship.
Antony Leather
The multi-threaded test sees a similar result — the Ryzen 7 3800X sitting level with the Core i9-9900K and a huge amount faster than the similarly-priced Core i7-9700K and also offering a massive boost over the Rzyen 7 2700X too.
Antony Leather
HandBrake
Intel might claim that Cinebench is maybe not an entirely relevant test given its small userbase, but the fact remains that you’ll see similar results in other multi-threaded tests too such as HandBrake, where once again the Core i9-9900K was matched by the Ryzen 7 3800X.
Antony Leather
PC Mark 10 Image Editing
PC Mark 10’s image editing test seems to love AMD CPUs with even the Ryzen 7 2700X offering similar results to the Core i9-9900K with the Ryzen 7 3800X way out in front.
Antony Leather
Power Consumption
Despite offering significantly more performance than the Core i7-9700K in multi-threaded tasks the Ryzen 7 3800X system drew similar amounts of power from the wall and once overclocked offered massive power savings while matching or bettering the Core i9-9900K in content creation tests.
Of course, in games, power consumption would be lower overall, but these results are significant for anyone planning to use their new CPU for heavy multi-threaded work.

Conclusion
The Ryzen 7 3800X is a little quicker at stock speed and offered some extra overclocking headroom over the Ryzen 7 3700X, but ultimately the latter is better value at current pricing. If you’ve set your heart on the Ryzen 7 3800X, though, and want to know whether to buy it or Intel’s two 8-core CPUs, it isn’t quite as clear cut. In content creation and multi-threaded workloads, AMD is the clear winner, matching or bettering the more expensive Core i9-9900K.
In games, as usual it’s very title-dependant. Far Cry 5 saw the Core i7-9700K perform brilliantly and even better the Core i9-9900K, which was also out-done by the AMD CPU.
Shadow of the Tomb Raider and Dota 2, though, both preferred Intel, but the differences here were usually less than those between the two companies in content creation, and will be even less at higher resolutions. For pure-gaming systems, Intel still has a slight advantage, but outside of games, things swing massively in AMDs favor both in terms of value and raw performance.

Ryzen 7 3800X
- The Ryzen 7 3800X has higher Level 2 Cache.
Data/instructions which have to be processed can be loaded from the fast L2 and the CPU does not have to wait for the very slow DDR RAM - The Ryzen 7 3800X has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
- For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
- The Ryzen 7 3800X has a smaller process size. The faster a transistor can toggle on and off, the faster it can do work. And transistors that turn on and off with less energy are more efficient, reducing the operating power, or “dynamic power consumption,” required by a processor.
i9-9900K
- The i9-9900K is more power efficient and generates less heat.
- The i9-9900K has a higher turbo clock boost.
Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.

Which CPUs are better?
impressions of the new line of processors / Sudo Null IT News
Tonight, AMD introduced a new family of Ryzen 7000 processors.
We studied the benchmarks and now we are thinking which processor to take for testing in the Selectel Lab. What would you choose? Voting is under the cut.
Main differences from the previous generation Ryzen 5000:
- Zen 4 architecture, 5nm instead of 7nm dies,
- new Socket AM5 with support for DDR5 memory, PCIe 5.0 interface,
- integrated graphics on all processors of the line,
- significant increase in base and maximum frequencies,
- L2 cache increase,
- improved performance and energy efficiency.
The company also introduced four chipsets for socket AM5 motherboards: X670 Extreme, X670, B550 Extreme and B550. More productive and, as a result, more expensive X670 will be available in September, and B550 — from October.
What has changed?
The table shows the specifications of the previous generation AMD Ryzen 5000.
According to AMD, the performance increase per IPC clock will be up to 13% and up to 29% single-threaded performance.
Characteristics on the example of the top processor AMD Ryzen 9 7950X:
- base frequency increased from 3.4 GHz to 4.5 GHz
- maximum frequency changed from 4.9 GHz to 5.7 GHz
- doubled L2 cache
- TDP increased from 105W to 170W
- added integrated graphics, in the AMD Ryzen 5000 generation it was only available in the 5700G and 5600G models
The younger models also do not lag behind in the increase in base frequencies. With such changes in the characteristics of processors, the declared growth looks expected. The use of faster and more powerful DDR5 and PCIe 5.0 will further increase system performance.
Application performance improvement
At the presentation, a comparison of the benchmark results of the new AMD Ryzen 9 7950X processor against AMD Ryzen 9 5950X in applications was presented:
- V-Ray Render: + 48%
- Blender Render: +30%
- Cinebench R23 nT: +48%
- POV Ray: +45%
A significant increase in performance, rendering speed and data processing is visible.
Similar results were obtained when testing the operation of processors in gaming.
The performance gain of the Zen 4 architecture compared to Zen 3 in various benchmarks is from 4 to 39%.
Prices
The start of sales is scheduled for September 27, the prices are announced as follows:
AMD Ryzen 9 7950X — $ 699
AMD Ryzen 9 7900X — $549
AMD Ryzen 7 7700X — $399
AMD Ryzen 5 7600X — $299
Prior to launch on Amazon (shipping in the US), the previous generation is discounted:
Ryzen 95950X — $546
Ryzen 9 5900X — $370
Ryzen 7 5700X — $ 279
Interesting arithmetic: with the declared increase in performance in benchmarks up to 45%, the discount on the previous generation was 20-30% of the price of new hardware. Do not forget that DDR5 memory is still more expensive than DDR4, and motherboards with socket AM5 at the start of sales will be expected to cost more than AM4.
All this will affect the final cost of assembly.
Competing with Intel
AMD compared the new Ryzen 9 7950X with the Intel Core i9-12900K and got the following benchmark results:
- V-Ray Render: +62%
- Blender Render: +36%
- Cinebench R23 nT: +41%
- POV Ray: +41%
Particular emphasis was placed on rendering efficiency combined with low power consumption.
Not surprising, given the difference in TDP processors. At the same time, Intel positions 8 of the 16 cores of the i9 processor-12900K as energy efficient and runs in 24 threads versus 32 for the 7950X. This affects performance in favor of AMD.
However, the Intel Core i9-12900K is priced at $569 on Amazon, which is $130 or 19% cheaper than the new AMD Ryzen 7950X.
Not spared performance benchmarks in games. The entire line of Ryzen 7000 processors presented in AMD’s presentation turned out to be more powerful than the i9-12900K.
