The 64-bit chips, code-named Antares, contain two processing units per chip, each with their own execution core and Level 1 cache. Additionally, each core includes a storage subsystem with 1MB Level 2 cache, making the chips twice as efficient as IBM's current 970FX PowerPC G5 processors.
Despite of the fact Apple announced a few weeks ago they were switching from PowerPC to Intel processors, the move is expected to take at least a couple more years, making the new dual-core processors a logical step forward for upgrading its existing line of Power Mac G5 and iMac G5 systems.
Additionally, IBM announced the launch of new low-power PowerPC 970FX processors that will run at 1.4 GHz to 1.6 GHz, while operating at less than 20 watts.
