| Awhile back I ran some tests using the Bytemark (Motorola version) benchmark. Although ByteMark performance is greatly affected by compiler versions used (the Motorola compiled version runs fastest) the results showed my PowerBook G3 (no extensions loaded) has better Integer and Floating Point performance than my Pentium II 300mhz system. With the Pentium II running at 75mhz bus/338mhz CPU speeds it just barely edged out the PowerBook G3 in Floating Point, but still trailed in Integer performance by a good margin. The PowerBook G3 was tested with a backside cache speed of 100 Mhz (stock) and at 166 Mhz using PowerLogix's G3 Cache Utility. (Few PowerBook G3 models seem able to run 166 Mhz cache speeds reliably but this one does).
Both systems had 128MB of Ram and 512k of 2:1 cache. The lower two scores were taken with the PowerBook G3 cache running at 166mhz (using PowerLogix's G3 Cache Utility), Libmoto and Speed Douber 8 active. The PII 300 used a ABIT LX6 Motherboard set to 75mhz bus, 4.5X ratio (337.5mhz, 1/2 speed 512K cache). I'll be running the same test in the future on all CPU cards and systems as part of the standard review benchmarks.
