IBM Power5+ chips going high-end Tuesday

Answering Intel's "Montecito" processor launch this week, IBM on July 25 will announce new high-end Unix servers using its own Power5+ processor, sources familiar with the plan said.

The Power5+ processor, a faster successor to the Power5 that's used in the existing top-end 32-processor p5-595, is expected to run initially at a top speed of 2.3GHz.
