Apple in recent years has sought to close the megahertz gap with Intel and Advanced Micro Devices by selling high-end machines that come with two processors instead of one. Thus, a dual-processor 1.2GHz G4 can reasonably claim to compete with a 2.5GHz Intel box. But Intel reckons there’s more than one way to build a two-brained beast and is experimenting with putting two processor cores on a single piece of silicon. It’s a process that CNET’s News.com says over the next decade will improve performance and reduce power consumption. One advantage is the ability to better dissipate heat. When a series of calculations has Core A chugging along at full steam, its transistors can hit temperatures that start to degrade performance. When that happens, the chip can “hop” some of the work over to Core B for an overall performance improvement. Another approach is to have Core A and Core B specialize in different things, similarly spreading the number-crunching responsibility around.
