Mountain House (CA) – Unlike the ATI that we knew before, it appears that AMD’s graphics division is running perfectly these days – and ahead of deadlines. Even though the graphics unit has posted an $8 million loss in the first quarter of this year – in

Biggest bottleneck is the 256-bit memory controller for both nVidia and ATI/AMD. Once they hit the 512-bit memory controller I think we will see a new evolution in performance.

That's why the 2900XT with the 512 controller was soooo much faster than anything on sale now?

more bandwith dont mean better performance.

Actually, the 2900XT is doing fairly well in speed, but the 512 controller was not the cause of its problems. Besides cost, one reason that both ATI and Nvidia are staying with 256 controllers is because the rest of the computer doesn't make use of the increased bandwidth. Its kind of like driving a car capable of going 200 mph in a 65 mph speed zone. All the extra power is wasted, so why bother?
