Hasta La Gadget!

If you’re scoring at home, NVIDIA currently holds the lead in single-GPU graphics cards with its GeForce GTX 580, but ATI’s dual-chip Radeon HD 5970 has been holding down the absolute speed crown for a good long while. Now, bearing the name of AMD Radeon HD 6990, its successor sidles up to the throne and demands attention as the fastest single expansion board you can plug into your shiny new motherboard. The 6990 boasts a massive 4GB of GDDR5, 3,072 Stream Processors, 64 ROPs, and an 830MHz core clock speed. A dual-BIOS switch will let you crank that clock up to 880MHz with a corresponding increase in voltage, but don’t expect to see much overclocking headroom above that.

Reviewers note, alongside their fawning assessment of the world’s best performance, that the HD 6990 is a massively power-hungry card (375W TDP) and one that makes quite a bit of noise while going through its herculean tasks. That’s in spite of a new vapor chamber cooling system that allegedly supports up to 450W of thermal output. If all this strikes you as a somewhat flawed execution, maybe you’ll join us in hoping NVIDIA’s imminently upcoming response, dubbed the GTX 590, will be able to offer a neater, more efficient assault on the extreme peaks of graphical performance.

Multiple cores are old hat, particularly in the GPU world where you can have hundreds of simultaneous processing units working in concert, but multiple GPUs on the same PCB, that’s still exciting territory (not least because of the crazy thermal and power requirements that go with it). AMD and NVIDIA are set to clash horns on this field of battle once again, fishing for mindshare as much as they are for high premium sales, with the Radeon HD 6990 and GeForce GTX 590, respectively. The former has already slipped out of the shadows of mystery to reveal a size slightly longer than an A4 sheet of paper, while the latter is being rumored for an unveiling at the PAX East 2011 gamer gathering. Expected GTX 590 specs include 1024 total CUDA cores, 3GB of onboard RAM with dual 384-bit memory controllers, and three DVI outputs for some single-card 3D Vision Surround gaming. This year’s PAX East is kicking off on March 11th and AMD is also looking very close to launching its part, so you should need no more than a couple of weeks’ worth of patience before everything about the latest and greatest from both camps is known.

Ah, NVIDIA, how far you’ve come. This time last year we were all wondering if your first Fermi GPUs would operate successfully without a nuclear reactor in our backyards, yet today you’re introducing a successor to one of the best value-for-money GPUs the PC gaming world has seen in ages. Yes, the GTX 560 Ti has mighty big shoes to fill, but it’s off to a good start with 384 CUDA cores running at 1645MHz, 1GB of GDDR5 RAM running at an effective rate of 4GHz, and an 822MHz graphics clock — each one a clear and pronounced upgrade over its GTX 460 predecessor. You’ll have to check out the reviews below for a detailed breakdown of what those numbers will mean on a game-by-game basis, but there’s another way in which this new card is proving its impact already.

ATI AMD has (conveniently) chosen to cut the prices of its Radeon HD 6870 and HD 6950 cards today, while also outing an HD 6950 with just 1GB of onboard memory to serve as a direct competitor to NVIDIA’s latest. Competition, ladies and gentlemen, it’s an awesome thing.

It’s baaack. We’ve gone well over half a year without hearing a peep from black magic makers LucidLogix, but here on the doorstep of CES 2011, the company has resurfaced just in time to ride on the coattails of Intel’s forthcoming Sandy Bridge platform. Sandy is expected to take over CES when companies start to introduce new PCs in just a few days, and thanks to Lucid’s virtualization software, we wouldn’t be surprised if a few are served with NVIDIA and AMD GPUs. This here technology enables the two to play nice, making the outlandish fantasy of using a multi-GPU, multi-vendor setup a reality. DirectX 11 is also supported, with the only real requirement being to “connect the display screen directly to the motherboard’s Sandy Bridge display output.” We’ll be taking a closer look at the peacemaker once we land in Vegas, but for now, go ahead and prepare yourself for a beta version of ‘Virtu’ — it’ll hit at some point next month.

It’s taken AMD a long time to refresh the top end of its graphics hardware, but today’s culmination to that wait has to be described as somewhat bittersweet. Sweet, because we’re finally getting a successor to the venerable HD 5870, one that offers improved power management and tessellation performance at a lower $369 price point, but also bitter because in terms of sheer firepower, the Radeon series doesn’t seem to have made quite the leap many of us had hoped for. The new top of AMD’s single-GPU pile, the HD 6970, offers 1,536 stream processors, an 880MHz core clock speed, and 2GB of GDDR5 RAM running at 5.5GHz for a total of 176GBps of memory bandwidth. Its partner in crime, the HD 6950, is expected to list at $299, for which saving you’ll have to sacrifice some clock speed (down to 800MHz) and processing units (1,408 in total). There’s a neat little addition to both new boards: a Dual-BIOS switch that will act like Google’s hardware jailbreak toggle on the Cr-48, allowing tweakers to unlock the extra (unprotected by warranty!) performance headroom in their cards.

Early reviews all seem to agree that both the Radeon HD 6970 and HD 6950 have struck a very fine price-to-performance ratio. The 6970 manages to spar with the much pricier GTX 580, but given that it’s priced similarly to NVIDIA’s GTX 570, it scores plaudits for being a more than viable alternative. The HD 6950 is seen as the real value item here, however, particularly since it occupies a relatively unique spot in the price range, and most reviewers tipped it as their new bang-for-the-buck leader.
