Rick - Re: ""G3", supposedly running 3X the speed of any PII out there. From Apple, as a PowerMac." Apple introduced their PowerMAC G3 Notebooks in November of last year with CPU speeds of 233 and 266 MHz. A month or so ago, IBM announced a PowerPC 750 (the official name of the "G3") with a clock speed of 275 MHz. Although IBM/Apple may have introduced faster versions, the 275 MHz is the fastest I am currently aware of. As for performance, the PowerPC and Intel chips were always pretty close (+/- 10 to 15%) in performance for integer operations. However, the PowerPC chips had much better FPU performance than the early Pentium devices. The Pentium Pro and Pentium II/Deschutes have much better FPU performance and are probably "close" to the FPU performance of the PowerPC/G3 - but still not quite as good. As for a factor of 3 (3x) - that would have to be some peculiar benchmark that for some reason performed dramatically faster on a PowerPC 750 (G3) than on a Pentium II. Of course, the 333 MHz Pentium II was probably not introduced when that commercial you saw was being made. As for Intel's Pentium II reaching 1000 MHz - no way! The fastest I have heard a Deschutes being tested to was 533 MHz - and I'm not certain under what conditions those were obtained - Power supply settings, heat removal techniques, etc. I would suspect the Katmai may be introduced at 500 MHz early next year - it will require newer memory architectures to feed the Katmai with data. Six months of non-obsolescence will be hard to obtain. Intel has a pot full of newer technologies and that pot is getting fuller. Intel is also ahead of the schedules they talk about for new processor introductions - so they (Intel) are forced to keep these CPUs under wrap because the market cannot absorb them at the same rate that Intel can make them. Intel's Technology Development TEAMS (plural) and Design Teams (Plural) are running at full tilt - and under control. Your 266 MHz Pentium II is a case in point. For example, the Deschutes was up and running in pretty good shape last July/August but was introduced just recently. Paul
