3dfx Voodoo Graphics EDO DRAM DAC frame buffer texture mapping unit EDO DRAM video controller RAM
Three former SGI employees had founded 3dfx in 1994. Their Voodoo Graphics extension card relied on PCI to provide cheap 3D graphics for PC's. Towards the end of 1996, the cost of EDO DRAM dropped significantly. A card consisted of a DAC, a frame buffer processor and a texture mapping unit, along with 4 MB of EDO DRAM. The RAM and graphics processors operated at 50 MHz. It provided only 3D acceleration and as such the computer also needed a traditional video controller for conventional 2D software.
