What Makes Apple's Power Mac G5 Processor So Hot

Posted by Hemos on from the learn-the-basics dept.

An anonymous reader writes "58 million transistors can drive a lot of power. Apparently, Apple appreciated the choices IBM processor architects made when designing the 970 family. This article provides the 64-bit architecture big picture for the 970 family (A.K.A. the Power Mac G5) and the critical issues in IBM's 64-bit POWER designs, covering 32-bit compatibility, power management, and processor bus design."

    Basically, we took one of our superchips that go into superservers, with a gitastic cache and frontside bus, stripped it down a bit so we don't cut into our own market, and gave it a new name. Isn't that cool?


    For us Apple users - you bet!

    Well, except for the fact that the processor's so hot, but you know what I mean :)

    bah the idiot is probably not running any applications.. load up seti at home or prime95 and let it burn in for a few minutes..

    Then touch your heatsink and tell me it's cool.

    Think he forgot about coolnquiet tech.. that proc probably runs sub 500mhz when idle.. so passive cooling works.
