I've been tracking the SPEC benchmarks of Pentium vs PowerPC for for almost two years now. macevolution.com macevolution.com At the same MHz PPC750 and 604e generally scores significantly higher than Pentium and Pentium IIs. The fact that SPEC suite runs on optimized hardware, and is often compiled with special compilers, on top of a lean OS makes it a terrible benchmark for evaluating real world performance. Under ideal conditions with simple problems to solve, a 4th grader can do almost as well as a mathematician. Similarly under ideal conditions with fast main system bus and specialized compilers, much of the superior features of PowerPC (such as larger cache, more register, better pipeline, RISC instruction set, onboard L2 cache tag) becomes less important. In addition, SPEC doesn't reflect the fact that PPC 750 has optimizations for MacOS to allow improved performance of real-world application. Even with all that PowerPC still comes out ahead against Pentium of the same MHz. Eric
