ATI Radeon 32MB SDR

CPU Scaling Performance

We purposefully benchmark all of the cards on a fairly high performance platform, in this case a 1.1GHz Thunderbird, in order to gain an understanding for the uncapped performance of the solutions. However, not everyone has a 1.1GHz processor so in order to get a better idea for what CPU speeds are necessary to get the most out of the Radeon SDR, we look to a CPU scaling graph to see how the card performs with various CPUs.

The performance improvements begin to level off towards the higher clock speed CPUs, indicating that other limitations are kicking in at that point. The Athlon, clock for clock, is only slightly slower than the Pentium III while using the Radeon SDR card. It seems like both CPUs have been taken advantage of fairly well by ATI's drivers, either that or there are very few platform specific optimizations at work.
