IBM RS64-III (Pulsar) processors
Introduction: 1999
PowerPC RS64-III 64-bit RISC microprocessor (also known as Pulsar) using copper technology. The RS64-III microprocessor powers the in September 1999 announced RS/6000 model 7017-S80 (450MHz). The frequency of 450MHz was accomplished by using IBM's new copper technology (CMOS 7S). The RS64-III has 8MB of Level 2 (L2) cache per processor. The 6-way SMP can be expanded to a 24-way SMP and the system memory can be expanded to 96GB.
