Processors
Whereas RS/6000 used a mix of early POWER and PowerPC processors, when pSeries came along this had evolved into RS64-III and POWER3 across the board—POWER3 for its excellent floating-point performance and RS64 for its scalability, throughput, and integer performance.
IBM developed the POWER4 processor to replace both POWER3 and the RS64 line in 2001. After that the differences between throughput and number crunching-optimized systems no longer existed. Since then System p machines evolved to use the POWER5 but also the PowerPC 970 for the low-end and blade systems.
The last System p systems used the POWER6 processor, such as the POWER6-based System p 570 and the JS22 blade. In addition IBM introduced during the SuperComputing 2007 (SC07) conference in Reno a new POWER6-based System p 575 with 32 POWER6 cores at 4.7 GHz and up to 256GB of RAM with water cooling.

Famous quotes containing the word processors:
“The information links are like nerves that pervade and help to animate the human organism. The sensors and monitors are analogous to the human senses that put us in touch with the world. Data bases correspond to memory; the information processors perform the function of human reasoning and comprehension. Once the postmodern infrastructure is reasonably integrated, it will greatly exceed human intelligence in reach, acuity, capacity, and precision.”
