Voodoo4 4500

The 3dfx Voodoo4 4500 card is based on a single VSA-100 chip operating at 166MHz. Like the much earlier Voodoo3, the VSA-100 chip is manufactured using a 0.25 micron six-layer process and contains 14 million transistors. The VSA-100 can output per clock either a pixel with 2 textures on it, or 2 pixels with one texture on each. Thus, the fill rate is 166 megapixels/333 megatexels in bitexturing mode and 333 megapixels/333 megatexels in monotexturing mode. For comparison, the GeForce 2 MX has a texturing speed of 350 megapixels/700 megapixels and the old GeForce 256 240 megapixels/480 megatexels in bitexturing mode, 480 megapixels/480 megatexels in monotexturing mode.

The Voodoo4 couldn't compete in speed with the GeForce2 MX and ATi Radeon. In all tests, both in OpenGL and Direct3D, the 3dfx card was inferior to its competitors. 3dfx positioned the Voodoo4 4500 in the budget PC market
