AMD issues graphic challenge to Nvidia

The usual battle for bragging rights between the two top makers of discreet graphics cards has clicked up a notch with the latest generation of gas-guzzling monsters issued by both AMD and Nvidia.

Senior bunny wrangler at AMD, Dave Erskine, has used his company blog page to issue to challenge to Nvidia, demanding that the outfit justify its claim to have produced the world’s fastest graphics card in the shape of its GTX 590.

AMD reckons its 'flagship GPU, the Radeon HD 6990 its the world's fastest graphics card, and it dug up a benchmark to back up its claim. The AMD Radeon HD 6990 achieved the highest default single graphics card score of X3303 using the industry standard 3DMark11 benchmark Erskine says.

Nvidia launched its GTX 590 a few days ago and issued a press release heralding it as the the world's fastest graphics card. Where's the evidence to back up such a claim? Erskine wants to know

"We combed through their announcement to understand how it was that such a claim could be made and why there was no substantiation based on industry-standard benchmarks, similar to what AMD did with industry benchmark 3DMark 11, the latest DirectX 11 benchmark from FutureMark," Erskine writes.

"So now I issue a challenge to our competitor: prove it, don’t just say it. Show us the substantiation. Because as it stands today, leading reviewers agree with us here, here, here, and here that the AMD Radeon HD 6990 sits on the top as the world’s fastest graphics card."

Nvidia, a past master in obfuscation, produced some benchmarks on its own site that compare the GTX 590 to its previous-generation cards, but like Erskine we're struggling to find any comparison to AMD cards anywhere. The ball's certainly bobbing about in the green goblin's court.
