With the debut of the IBM eServer™
pSeries™ 650, IBM recaptures the mantle of technology and performance leadership in the
eight-way server arena. Numerous benchmark results have been submitted for approval to the
Standard Performance Evaluation Council (www.spec.org) in
November 2002 to substantiate this, including SPECweb99, SPECjbb2000, SPECsfs97,
SPECfp_rate2000 and SPECompM2001. The p650 constitutes significant functional
enhancements when compared to predecessor products, such as the pSeries 660
Model 6M1. This paper explores some of the architectural and performance
differentiators between the p650 and the p660-6M1.
