First we want to compare the technical data of the rivals:
The main differences between the GeForce3 cards are the different chip and memory clock, resulting in a higher memory bandwidth, pixels and texel fill rate. However, the Radeon 8500 still has the highest chip and memory clock and therefore the largest memory bandwidth. This apparently results in the higher pixel and texel fill rate. The Radeon 8500 has its own graphics engine, which is designed for DirectX 8.1 and, like the GeForce3 cards, uses pixel and vertex shaders. The Radeon 8500 uses its own anti-aliasing process, Smoothvision.
