Sometime in early 2006 ATIÂ’s high-end lineup is likely to be refreshed with code-named R580 graphics processor, which is more powerful than ATIÂ’s R520 GPU.
Anyone who doubted ATI should really eat their words now, not only is the r520 coming in the next quarter, ATI pulled an ace out of their sleeves and announced an even more powerful GPU coming in early 2006. Anyone can do the math that nVidia has to pull some 7900 ultra out since the r520 is already more powerful than 7800GTX. nVidia may have been the first out of the gate but I must say I am impressed with ATIs hardwork as of late. I can pretty much assume the r580 will be a minimum of 40 pipes.
