    The PowerPC line does not max out at 1.67 GHz. The 7448 and 970MP are available up to 2 GHz.

      PPC 970, the G5, officially maxed out at 2.7 Ghz

    Hmm, why did G5’s require extreme cooling design if they really do not consume huge amounts of power or generate significantly more heat? Why was there no portable G5 if their power consumption was low? I’ve had couple G5 iMacs and they do run really hot under stress and still they mainly compete with Athlon XP in terms of perfomance, Dual G5 2.0GHz model even lost to a single core Athlon64 when it was benchmarked by one site, can’t remember the name but Google will find it.

    All i know is , useing powerpc macs felt way different than intel macs. i know intel is now faster, but something about the power pc chips felt smoother.

    This is the good exemple of article filled with many errors….

    IBM has produced Power processors running of 5Ghz…
    Freescale produces PowerPC processors with 12 cores, with low power consommation… able to deliver over 300 billions of operations per seconds, far over of what Intel can deliver as computing performance…

    But of course, with billions of dollars spent by Intel in marketing, for sure, Intel processors must be the best ones.

      Absolutely right, POWER6 is able to run on 5 GHz with nominal cooling techniques, while the intel chips needs water cooling and huge fans at this clock rate.
      Not mentioning the instruction set, the x86 core is still the i386 from 1985 but they are still keeps it, to make it able to run winshit.

    The G5 is only one of the PPC family. The G4 and earlier models were comparatively low power and cool running processors. Modern ‘Power’ chips generally follow that trend. The 970 ‘G5’ was an attempt by IBM to leapfrog Intel with the first 64 bit consumer PC whilst catching up in the all important MHz war… something that even today blinds people to the truth of how well a processor actually performs. IBM simply didn’t get enough revenue from the desktop PPC market to make further investment worthwhile. Big iron and embedded markets were the real markets for Power CPUs, while Intel and AMD dominated the consumer market, with all the benefits economies of scale bring.
