Things are hotting up in the world of dedicated graphics cards, and by that I don’t mean the Nvidia GTX 590s that have been sparking and smoking after people have upped the voltage as part of an overclock. While a smoking card is obviously more than just warm, AMD is steaming towards Nvidia in their latest blog post, after Nvidia’s marketing team has stated the GTX 590 is “the world’s fastest graphics card” — essentially calling them out and asking them to prove it.

“Two weeks ago we launched our flagship GPU, the AMD Radeon™ HD 6990″, reads the blog post written by Dave Erskine, AMDs desktop graphics Senior Public Relations Manager. “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.  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.”

Then, the post really throws down the gauntlet when it continues to read: “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.”

Personally, I’d be happy to have either the GTX 590 or HD 6990 sitting in my rig, so if the 590s aren’t fast enough just throw them this way. I look forward to seeing whether or not Nvidia can come out and disprove AMD’s claims, I guess we’ll have to wait and see.
