I'm working here with a defective onboard L2 cache and with a single 256 MB RAM module. The only explanation I have, is the difference in cache on the CPU.
(Tyan S1590S early version, 256 MB PC100 RAM, 20 GB HDD, Creative S3 Savage 4 PCI, Voodoo 2 8MB, and a CT2230)

SiSoft Sandra is not practical, so only the results of the 3D Mark.

What do you think? With a few exceptions such as the theoretical CPU benchmarks in SiSoft Sandra and a few DOS tests, the K6-III 450 is better despite being clocked 50 MHz less.
