Nvidia GeForce GTX 760 review

Our Verdict

A great little mid-ranger, and a perfect reward for those gamers whove been putting off their GPU upgrade.

Component manufacturers love the bombastic use of military speak and the double whammy of GTX 700 series releases from Nvidia certainly have something of the shock-and-awe about them. This latest card, the Nvidia GeForce GTX 760 is no different, and sets to the middle order of AMD’s competing Radeon graphics cards.

It’s rare though that Nvidia and AMD don’t decide to launch their new graphics generations — whether they’re whole new architectures or range refreshers — at around the same time. Generally there’s only a few months between them at worst, with Nvidia normally the ones turning up late to the party, blaming the traffic on the way over or difficulties in hitting decent yields with new process nodes.

This time though it’s Nvidia who are the first to arrive, eagerly clutching their new silicon, with AMD kicking their heels back in Texas. But this apparently is not a delay, AMD have decided they are going to stick with their current range of HD 7000 GPUs until the end of the year, so confident are they in their existing cards. I’ve got to believe though somewhere there are some AMD Radeon execs who are sweating just a little more now.

When the GTX Titan and 780 dropped on the scene I’m sure they weren’t that fussed — those two cards sit almost entirely out on their own and are catering for a customer that arguably AMD isn’t servicing right now. But the price and performance of the GTX 770 must’ve been a real kick in the nuts. And now the GTX 760 is nipping in after and stealing AMD’s wallet while they lay there clutching their groin.

This is getting close to the real volume segment of the graphics card market then, and at £209 / $249 GTX 760 is really going to knock chunks out of some of AMD’s biggest selling cards. I expect the HD 7950 has been a right good earner for them, but this new Nvidia card is often times faster and always cheaper. In the UK you’ll actually find a PNY reference version for less than £200 today.

Sadly, for AMD, it’s the same story in comparison with the HD 7870 XT — one of my favourite cards of the last generation. That Tahiti LE-based card used to retail around £170 in the UK, and there was nothing at that price to rival it. Unfortunately, possibly thanks to a combination of popularity and scarcity, they’re right now far pricier.

So, what’s in the GTX 760? Well, it’s a little different to the GTX 770 in that it’s 600 series twin is harder to distinguish. The GTX 770 was, after all, a barely disguised GTX 680, which was no bad thing when it turned up at the same price the GTX 670 is still sitting at. You might then think the GTX 760 would simply tip up with the same spec as the GTX 670 but at the same price as the GTX 660.

Well, it doesn’t. What we have is a spec more similar to an OEM version of the GTX 660, which never ended up in my labs. The GeForce GTX 760 then comes with 1,152 CUDA cores and runs at a 980MHz base clockspeed with 2GB GDDR5 video memory running at around 6GHz. The ol’ GTX 670, the pricier elder statesman, has 1,344 cores, which is where it retains its performance lead over this newer, cheaper card.

Elsewhere though the GTX 760 is holding onto some high-end component specs. That 2GB GDDR5 is running along a relatively chunky 256-bit memory bus and the GPU is running with a full complement of 32 ROPs. In performance terms that translates to a pretty consistent lead over both the Radeon HD 7950 and the HD 7870 XT in the majority of tests, with only DiRT Showdown offering AMD a genuine performance lead. Nvidia still hasn’t sorted out the issues its hardware has with the global illumination in Codemaster’s racing engine.

Outside of Crysis 3, and the heavily-detailed Sleeping Dogs benchmarks, the sort of performance I was seeing from the GTX 760 makes it not a bad card at 1600p, let alone 1080p. In some of the gaming tests it was knocking around 30fps or higher at 2560×1600. Even taking the tougher tests into account it’s rare that the GTX 760 minimum frame rate drops much below 30fps at 1080p. You can thank the 256-bit bus for a good deal of that.

Sadly, despite the GPU Boost 2.0 shenanigans, there’s not really anywhere to go in terms of overclocking the GTX 760. At stock settings GPU Boost 2.0 has the chip running at 1,136MHz under load, but even if you push the reference card to its limits at 1,254MHz I wasn’t seeing much in the way of performance benefits. That’s going to make it tricky for us to get behind the factory-overclocked cards, like the EVGA GTX 760 Superclocked card, but you can find out all about that in our GTX 760 Superclocked review .

It’s a powerful little card at stock speeds though — and I would hope to see some impressive small-scale versions too thanks to the reference card’s shorter PCB too. For the money Nvidia have set out as the MSRP — just over £200 / $250 — the GTX 760 is looking good to take over the mid-range graphics market. If you’re looking to upgrade your graphics card now, with a £200 / $250 budget, this is as good as it gets.

But who should be upgrading? Well, that all depends on the card you’re running at the moment and the native resolution you’re going to be gaming at. If you’re running at a standard 1080p resolution then pretty much any £150 / $200 card of the last generation will still be giving you decent frame rates in the latest games. And the top cards of the generation before are still gaming happily away at that resolution too.

But right now AMD have really got to pull their fingers out and make sure their HD 8000 series really delivers some serious performance leads over their current hardware. The GTX 700 series has upped the price/performance level another notch. And AMD will need that lead too if Nvidia’s new Maxwell GPUs manage to come out on time in early 2014.

Benchmarks

All of these benchmark tests were run on the same stock-clocked i7-3770K setup with an Asus Sabertooth Z77 motherboard and 16GB of Corsair Dominator RAM running at 1,600MHz. The gaming tests ran at top settings with 4xAA (with the exception of Crysis 3 which is a bast when it comes to AA) and these figures are from the 2560×1600 benchmark runs. The first number is the average frame rate and the number in parentheses is the minimum frame rate achieved.

You can see the overclocked EVGA card only delivers a couple extra FPS here and there, with the HD 7950 lagging behind too. There are a few places where the AMD card can claim some parity with the new Nvidia mid-ranger in performance terms, but the GTX 760 is still retailing a good chunk cheaper.

AMD might need to at least start slashing prices if they want to get competing again.

Nvidia has successfully perked the graphics market from its mid-cycle stupor with the launch of the GTX 760 2GB. Sat at the mid-point between the mid-range £150 GTX 660 2GB and high-end GTX 670 2GB, the stock 760 2GB already performance close to the GTX 670, leaving plenty of opportunity for board-partners to bridge the gap.

MSI’s take on the GTX 760 2GB is the GTX 760 Twin Frozr Gaming OC 2GB, a significantly up-rated version of the card in almost every way, not least PCB size. While the stock 760 runs a dainty 175mm PCB and requires a pair of 6-pin PCI-E power connector, the Twin Frozr Gaming’s PCB is a lengthy 260mm and requires an 8pin and a six-pin power connector; the same connectors as a stock GTX 770 2GB.

While the PCB might have been extended, the basic feature set and layout of the card, and the GPU, remain the same. To the rear are a pair of DVI outputs as well as full-size DisplayPort and HDMI ports (with support for up to four simultaneous displays), while a pair of SLI gold-finger connectors on the top of the card support up to four of the cards in SLI.

Those looking for a recap of the GTX 760 GPU would be best served by reading our stock card review, but the Twin Frozr Gaming’s GPU is no different physically. The GPU is still a 28nm GK104 chip, sporting six SMs of 192 stream processors for a total of 1,152 stream processors. While this is actually fewer steam processors than the GTX 660 Ti 2GB (the card the GTX 760 2GB replaced) the GTX 760’s full-size 256-bit memory interface and array of 32 ROPs allow it to out-pace its predecessor.

Of course, one area of the GPU that MSI has been able to improve is its clock speeds, with the Twin Frozr OC boasting a fairly healthy factory overclock. As with all Nvidia’s GeForce 7-series cards, it uses GPU Boost 2.0 to automatically adjust the clock speed between a base clock, a guaranteed boost clock and a best-case boost clock. While the stock card’s 130MHz boost curve starts at 980MHz, the Twin Frozr OC’s begins 40MHz higher at 1,020MHz, boosting to a guaranteed 1,073 and a maximum of 1,150MHz. This is actually a rather timid 4 per cent overclock, especially when you add the fact that the card’s 2GB of GDDR5 is clocked at the stock frequency of 1.5GHz (6GHZ effective).

Click to enlarge — The 1GB of GDDR5 on the rear of the PCB is bare and not actively cooled.

However, the Twin Frozr OC’s got an extra trick up its sleeve courtesy of MSI’s generically named ‘Gaming App.’ This simple bit of software allows you to instantly switch the card between three different clock speed profiles; OC, Gaming and Silent. It’s the OC profile that’s most intriguing, as this further boosts the card’s base clock by an additional 45MHz. Of course, you could just as easily add those extra few MHz using MSI’s Afternburner overclocking utility, but MSI’s push to grant that extra performance to those who perhaps aren’t so tech savvy is a welcome one.

Aside from its clock-speed shenanigans, the Twin Frozr OC also improves Nvidia’s GTX 760 recipe in the most obvious way; the cooler. The stock card, at stock frequencies and settings will easily bounce off its 81°C thermal ceiling and begin to clock itself down a bit, so MSI’s solution is fit the latest version of its well-regarded Twin Frozr cooler. This updated version uses a pair of 100mm down-draft cooling fans fitted atop a huge array of aluminium cooling fins. Pulling heat from the GPU core and dispersing it through the fin stack are four nickel plated copper heatpipes, with the GPU sandwiched beneath a nickel plated contact plate to ensure all four heatpipes make good thermal contact with the small 294mm² die.

MSI’s modifications go further than just bolting a big cooler to the GPU though. There’s also a sturdy aluminium plate affixed to some of the power circuitry and the GDDR5 modules on one side of the GPU. As well as cooling the component, this also has the added benefit of adding rigidity to the card to reduce board-bend over time, although the further 1GB of GDDR5 on the PCB’s back side is bare and receives no cooling.

The power circuitry itself uses five phases for the GPU and a separate pair of phases for the memory, with 7+1 phase power for the card overall. Despite this, Nvidia’s stangle hold on its GPU voltages remains and regardless of OC software you’re only able to add a measly 12mV of additional power to the VCore.

With a monster cooler and a decent factory overclock, lets find out how the Twin Frozr OC fared in our benchmarks, and more importantly, when overclocked.

ASUS GTX 760 DirectCU Mini OC Review

Closer Look

To keep the heatsink and thus the core cool ASUS have used their new and advanced 360-degree CoolTech axial fan. Even in DirectCU Mini form, the proprietary design delivers up to 20% (claimed) cooler temps and three times quieter performance than reference.

Again, we see the dreaeded sticker of doom. Remove or destroy this stick and you will invalidate the warranty of the GPU. ASUS clearly do not want you to remove the cooler as the only way to do so is to break this sticker which covers one of the spring loaded screws holding the GPU to the heatsink.

After removing the heatsink (thereby ending the cards warranty), we see that the DirectCU mini cooler is made up of a vapor chamber which has direct contact to the GPU core. The TIM used was like glue, so much so that it took much more ‘persuasion’ than usual to break the seal between Core and heatsink. Removing the TIM was also very difficult as it had set like concrete! Thankfully our sample had very good contact with the core so if our example is anything to go by, you should have little need to break the warranty and replace this TIM.

The PCB is the same size as the reference design and a similar layout. Half of the memory is on the core side while the other is exposed on the rear. The VRM is furthest away from the power socket and has also been tweaked slightly.

The voltage regulation module is a 4+1 power phase design and is made up of ASUS’ ‘Supper Alloy power’ modules. These allow for 30% higher voltage threshold. Dedicated SAP CAPs and alloy chokes ensure those crucial overclocks are reached without the resonance/buzzing of traditional power chokes.
The Direct Power design acts as a highway between components and the GPU. Rather than having a single route which causes electron congestion, the Direct Power allows for alternate routes for a cleaner power delivery which lowers impedance (-56%) and thus PCB temperature (-7.4c).

The memory modules are HYNIX and carry the product code of H5GQ2h34AFR R0C which means while they are the same ones used on the reference design, they overclock exceedingly well.

The final piece in the jigsaw is the beating heart of the GTX760, the 6 x SMX GK104 core.
