Specifications

Equipped with two VSA-100 chips running in SLI (Scan Line Interleaving), this card is capable of twice the performance of the Voodoo 3. Both processors divide the 64MB of on-board SDRAM equally among themselves with each processor getting its own 32MB chunk. The downside to this method is that textures have to be copied to each chip's memory bank, so effectively this card is only 32MB.

The V5 5500 PCI's specs are almost exactly the same as the AGP version's:

• Integrated 256-bit 3D/2D
• 32 MB SDRAM per chip (64MB Total)
• 166MHz/166MHz core/memory clock
• 5.3GB/s Memory Bandwidth
• 350MHz RAMDAC
• 667 Mpixels/s fill rate
• .25 micron (enhanced) manufacturing process
• Dual pixel pipeline
• 32-bit rendering
• 2Kx2K maximum texture size support
• Single-cycle trilinear mipmapping
• Up to 24-bit floating point depth buffer (Z and W)
• 8-bit stencil buffer
• 2X and 4X full-scene hardware anti-aliasing
• DirectX texture compression and 3dfx FXT1 texture compression
• T-buffer technology
• Depth-of-field blur
• Motion blur

Real-Time FSAA in a nut shell

The most notable (and most useful in today's games) T-Buffer feature of the Voodoo4/5 series is its ability to do full scene spatial anti-aliasing. Full Scene Anti-Aliasing helps to eliminate the "jaggies" that plague all 3D games, especially those played at lower resolutions. 3dfx accomplishes this by basically rendering the image two to four times (at slightly different/offset positions than before), which effectively eliminates the "jaggies", pixel popping, and texture shimmering anomalies. 3dfx's implementation is great because it works with virtually all games, past, present, and future. 3dfx's implementation also looks the best compared to its competition's (manly Nvidia and ATI) FSAA offerings.
