Architecture Analysis R520 v G70
 

Imagine a world where all graphics cards were made more equal. One in which the latest 7800 used 16 pipelines and 450/1000 clocks and the X1800 used its 16 pipelines at 450/1000 speeds. Which would perform better, and under what circumstances? Well imagine no more as here today we have a 16 pipeline NV47 going head to head with a R520 at 450/1000.
