I think it's truer to say that PowerPC stalled in performance per watt. The high end Power7/Power8 chips are massively powerful but that comes with Power and Cooling requirements that aren't going to work in a laptop.
- gsnedders 13y agoThe high end POWER stuff always had crazy cooling, though.
- Millennium 13y agoThose post-date the G5 by several years, though. Things had gotten better for POWER by then, but it had already lost much of its market.
- whatusername 13y agoKindof true. I'd forgotten how much of a Mhz bump the P6 was -- It came out 12 months after the first intel Mac Pro (and ran at 4.7Ghz at the high end). The P5 was a contemporary of the G5 (although the G5 was really a P4). But it wasn't quite the beast the P6 was.
- gsnedders 13y agoAnd the G5 (the PPC 970 in IBM's nomenclature) was an "ultra-light" POWER4 — the POWER5 was ~30% quicker than the G5. POWER never really fell behind at the high end — there was just no real focus on anything except the high-end.
