TOPIC



    Isn't 68040 CPU (central processing unit) used in the Centris 650 the same as that used in the Centris 660AV and Quadra 660AV?

    If so, why is there not a heat sink mounted on the 68040 in the Centris 660AV and Quadra 660AV?

DISCUSSION


    Both the Centris 650 and the Centris 660AV use a Motorola MC68040 CPU running at 25 MHz.

    The original MC68040 25 MHz chips that came from Motorola required the use of a heat sink on the Centris 650 to reduce the amount of heat generated by the chip. A new version of processor now used in Centris 660AV and Quadra 660AV no longer require the heat sink.
