POWER2 and PowerPC architecture

Vol. 38, No. 5, 1994

Order No. G322-0194
During the four years since the RISC System/6000® (RS/6000) announcement in February of 1990, IBM has strengthened its product line with microprocessor enhancements, increased memory capacity, improved graphics, greatly expanded I/O adapters, and new AIX® and compiler releases. This special issue of the IBM Journal of Research and Development focuses on the POWER2 and PowerPC portions of IBM's wide-ranging announcement in the Fall of 1993. The new POWER2 processor nearly doubles the performance of the earlier high-end models.
