 ATI's initial response to GeForce 256 was the dual-chip Rage Fury MAXX.By using two Rage 128 chips, each rendering an alternate frame, the card was able to somewhat approach the performance of SDR memory GeForce 256 cards, but the GeForce 256 DDR still retained the top speed.ATI was developing their own GPU at the time known as the Radeon which also implemented hardware T&L.
