While Intel (NASDAQ:INTC) has stopped trying to maximize CPU clock speeds in favor of adding cores and improving efficiency, IBM is still at it. The next CPU to go into IBM's system Z mainframe line will have a clock speed of 5.5 GHz., and Big Blue's Power7+ CPUs (to be used in high-end UNIX/Linux systems) will have cores that surpass 4.5 GHz. IBM's chip division is struggling, but in this case, its efforts help differentiate a profitable server/mainframe business that in turn drives lucrative services deals.
