The rated clock speed ratio of core speed (MHz) to memory speed (MHz) of the ATI RADEON 9600 PRO chipset is 400/600 . Recently, I have come across some budget AGP cards from POWERCOLOUR and GECUBE, which have this ratio as 400/400 and 400/366 respectively. How will these variation in the memory clock speed affect the performance of the AGP cards ? AGP cards from CLUB and GIGABYTE have this ratio as the ideal 400/600. I presume these cards will be superior in performance than the earlier mentioned two cards from POWERCOLOUR and GECUBE.
