>>AAPL's chip is 64 bit RISC based whereas INTC's is 32 bit CISC . << Jim, actually the only PPC chip that has 64-bit implementation is PPC 620 which were use by Bull and IBM in some projects. All other PPC used in Macs are 32-bit implementations of the PowerPC design. Eventhough we all assume that PowerPC is a RISC chip, PowerPC actually has a very large number (100+) of instructions in its instructions set. Most other RISC chips supports only 30-50 simple instructions. PowerPC is kind of like a freak of nature. It's a very powerful design that uses the RISC architecture (in terms of pipeline, branch prediction...etc), and yet its complexity defies the fundamental RISC philosophy. PPC 620 project had some trouble a couple years back. I think they're back on track now. The performance of today's 604e easily surpassed the earlier 620s. Of course the 620 was designed for server applications so some of its strengths are not readily apparent if we just look at SPECint and SPECfp benchmarks. Eric
