That's a lot of features
We're most interested in the 2 multi-textured pixels per clock, the onboard T&L, and the DVD options. Current 3D accelerators such as the Voodoo 3 and TNT2 only do a single multi-textured pixel per clock. The Savage2000's 2 multi-textured pixels per clock virtually doubles the performance of the Voodoo 3 and TNT2, the Savage2000 can also do single-pass quad texturing for a single pixel.
S3 states that their transform & lighting engine S3TL "Enables Next-Generation Content with 4-10X Polygon & Lighting Complexity," with up to "8 dynamic hardware lights with 3X performance of today's CPUs." S3TL also features real time load balancing between hardware T&L and the CPU. The video card will be able to pump out far more polygons onto the screen, and we'll see even more realistic 3D games as programmers take advantage of the technology.
Current games don't even need the 3 million sustained triangles per second current 3D accelerators can push out. Fill rate is still the main bottleneck and will continue to be the bottleneck until games start using more polygons.
As for DVD playback, the Savage2000 can dynamically adjust up to 16 taps. The number of taps is the number of times the card filters an image. Most cards can only do 8 taps or less. The chip also supports a VIP 2.0 video-in port, digital flat panel and TV-out ports.
