ATI X300 with Hyper Memory waiting in the wings
 

ATI HAS AN answer for Nvidia's 6200 Turbo cache marchitecture. ATI went public with its architecture where it can address system memory and use it for a graphics card, but so far it hasn't launched a card supporting it.
ATI calls it "Hyper Memory" and its X300 chips are capable of supporting this marchitecture. It's not so big a deal for the noisy high end market, but all OEMs and system integrators just adore it. It gives them the power and right to say that a graphic card actually has 128MB of memory, even if the real graphic card has only 16MB or real dedicated graphic RAM
