"We had designed it to be a game-changer and we hit the bull's eye. The result: The AMD Radeon HD 6990 achieved the highest default single graphics card score of X3303 using the industry standard 3DMark11 benchmark," Erskine wrote.
"And when we launched it, we issued a press release in which we proudly called it the 'World's Fastest Graphics Card' and fully disclosed the basis upon which we made that claim."
Earlier this week, NVIDIA issued its own press release, announcing the GTX 590 graphics chip. They also claimed in the press information that the GTX 590 was the World's Fastest Graphics Card. Erskine said that the folks at AMD combed through all the available information, looking for anything that could substantiate NVIDIA's claim.
"So now I issue a challenge to our competitor: prove it, don't just say it. Show us the substantiation," he challenges, continuing on to drop no less than 4 links to reviews online that put the AMD Radeon HD 6990 at the top of the list of the fastest graphics cards on the market.
Hopefully NVIDIA will entertain us all with a response, one way or another.
