ATI’s R520 architecture, the new king of the hill? (X1800) : Preview

Quote: So what does the R520 architecture bring to the table exactly? For starters it is not the 32-pipeline architecture it has been rumored to be, it is half that, offering just 16-pipelines, which is less than NVIDIA’s G70 architecture that has 24. The R520 architecture will be introduced as the X1800 series, featuring the top-of-the-line Radeon X1800 XT with a 600MHz core clock and 700MHz memory clock, yielding an effective 1400MHz memory clock speed. The 600MHz clockspeed combined with 16-pipelines for the graphics processor will give it a lower fillrate than the GeForce 7800GTX though, although the 7800GTX’ graphics processor runs at just 430MHz. With 512MB GDDR3 memory connected by a 256-bit wide memory bus the X1800 XT boasts more memory than the 7800GTX, but as shown before with 512MB version of the GeForce 6800 Ultra this will usually not help performance much, if at all.
