Design Philosophy of the IBM PowerPC 970

D.J. Hodge writes "Ars Technica has a very detailed article on the PowerPC 970 up that places the CPU in relation to other desktop CPU offerings, including the G4 and the P4. I think this gets at what IBM is doing: 'If the P4 takes a narrow and deep approach to performance and the G4e takes a wide and shallow approach, the 970's approach could be characterized as wide and deep. In other words, the 970 wants to have it both ways: an extremely wide execution core and a 16-stage (integer) pipeline that, while not as deep as the P4's, is nonetheless built for speed.'"

    2h = second half
    03 = 2003

    In the case of Blizzard that means Fall 2005.

    It is highly unlike[ly] that Apple will go with a heat producing, energy wasting x86 Intel chip.

    ...because PPC chips completely disobey the laws of physics, producing neither heat, nor "waste energy" (perhaps through the production of heat?). Yes, it is PPC, miracle of modern technology, standing up for the common man against the perils of Thermodynamics!

    When I had the Pentium 4, she complained about its narrowness, but its was great. With the G4 Mac, it was nicely wide, but too short, she would note. I'm sure that with the 970, I can fulfill all her dreams!
