- The bandwidth to main memory is at least four times faster than
- 32-bit PCI. In tests against the 21164 reference design that DEC
- is working on and that we understand some clone vendors are
- attempting to spin into a product, the Raptor 3, running a series
- of Lightwave 3D test renders, was about 10 percent faster. The
- DEC board even had faster cache RAMs than did the Raptor 3 we
- tested against it and it was still 10 percent faster. DEC put a
- 256-bit wide bus to cache memory on the reference design. The
- Raptor 3 has a 128-bit bus. Why didn't the DEC design win? I
- don't know. Forget the techno-babble, real-life application
- tests are what matter. Raptor 3 wins . . . at least this
- round:-)
