3DMark wars: Nvidia and AMD go head-to-head on our test rig. Who wins?

The new version of Futuremark’s 3DMark has just been released, offering us all ways to benchmark our graphics cards and PCs by using Matrix-esque squid robots. And who wouldn’t want to be able to do that? I’ve grabbed the current top two single-GPU graphics cards from both AMD and Nvidia and have put them head-to-head in a battle royale to see who Futuremark's squid-bot believes is the quickest graphics card out there.

Asus unveils the RoG ARES II multi-GPU behemoth. Quake, mortals.

AMD has shown reluctance to release their own-brand HD 7000 range dual-GPU card, leaving affiliate manufacturers like Asus, Club3D and HIS to cobble together their own polygon-crunching beasts. As a result, we’ve seen a fair number of super-powered graphics cards over the last few months, including the freakishly potent Club3D Radeon HD 7990s - but with the unveiling of the Asus ARES II, things may just be getting a little silly.

AMD brings turbo boost to Radeon HD7970

Should you happen to be in the market for a $500/£420 graphics card, AMD has launched a new contender for your cash today. I say new, but it's more a makeover: the Radeon HD7970 Gigahertz Edition is physically identical to the current AMD flagship, the HD7970, with a couple of minor tweaks to earn it that big sounding suffix.

The first is, as the name suggests, an increase to the core clockspeed from 925MHz to 1000MHz. To go with that the 3GB of memory has been accelerated to a full six gigahertz equivalent speed, putting it on a par with NVIDIA's top end GTX 680. More interesting, however, is the fact that AMD has also caught up with NVIDIA by introducing a feature for accelerating the HD7970 depending on the processing load and chip temperature, something which the latest GeForce cards were well praised for.
