AMD trolls Nvidia with super-speed laptop GPU

AMD's announced the Radeon HD 6990M, a chip it's saying is the fastest laptop graphics processor in the world, up to 25 percent faster, in fact, than Nvidia's GeForce GTX 580M unveiled only two weeks ago with the same claim. AMD reckons the new Radeon kicks the puny GeThing to the curb when benchmarked on Batman Arkham Asylum, Dragon Age 2, Shogun 2, BattleForge, Left 4 Dead, Metro2033, Wolfenstein MP, The Chronicles of Riddick, and E.T.: Quake Wars. If this sort of thing makes you do the sex-wee, hit Engadget for specs and a PR.
