IBM’s microprocessor division is developing a dual-core version of its PowerPC 970 processor (called the PowerPC G5 by Apple), according to eWeek. The new chip, code-named “Antares,” will be designated PowerPC 970MP and will be available for testing purposes later this summer. “The PowerPC 970MP will contain two processing units per chip, with each carrying its own execution core, Level 1 cache and storage subsystems including a Level 2 cache. This move, according to sources at IBM, is intended to expand the PowerPC’s top frequency capabilities, currently at 2.5 GHz, in a dual-core configuration. The new chip will let vendors scale up server lines to a four-way SMP configuration.”
