PowerMagic ATI Radeon 8500 in the test: Swan song for the GeForce3?

Technology & Features

First we want to compare the technical data of the rivals:

Performance data GeForce3 Radeon 8500 chip clock 200 Mhz 275 Mhz memory clock 460 Mhz 550 Mhz memory access 3.8 ns 3.6 ns memory bandwidth 7.3 GB/s 8.8 GB/s rendering pipelines 4 4 pixel pipelines 2 2 pixel filling rate 800 MPixel/s 1100 MPixel/s Texel fill rate 1600 MTexel/s 2200 Mtexel/s Graphics engine nFiniteFX Engine DX 8.0 Smartshader DX 8.1 Vertex shader yes yes Pixel shader yes yes Anti - aliasing methods Multisampling, Quincunx Smoothvision DualDisplay support no yes RAMDAC 350 Mhz 400 Mhz

The differences are immediately noticeable - the Radeon has a much higher chip and memory clock than the Geforce3. The memory bandwidth is also a good 1.5 GB/s higher. 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, also uses pixel and vertex shaders. The Radeon 8500 uses its own anti-aliasing process - Smoothvision - which we will go into in more detail later. The Radeon 8500 has another plus point in terms of features with its dual display support, similar to the newer Matrox cards.
