POWER5
From Free net encyclopedia
POWER5 is a microprocessor developed by IBM. It is an improved variant of the highly successful POWER4. The principal changes are support for Simultaneous multithreading (SMT) and an on-die memory controller. Each CPU supports 2 threads; since it is a multicore chip, with 2 physical CPUs, each chip supports 4 logical threads. The POWER5 can be packaged in a DCM, with 2 chips per module, or an MCM with 4 chips per module.
