Geometry Performance
100% of setup and rasterization in silicon - typically 5M polygons per second
& geometry - typically əM delivered polygons/sec on a PIII
CPU geometry processing is not fast enough
- The fastest CPU cannot keep today’s rasterization silicon saturated if running the geometry in software
- CPUs geometry performance today trails rasterization silicon by > X3
- Workstation boards use geometry acceleration to offload geometry from the CPU
- Double hit - in reality the CPU is also running application code
