Power5 Processor Notes

CBROnline posts some details about the upcoming Power5 processor from IBM.

Bits of information about the Power5 has leaked out over the past few months, with an expected target date of Q2 2004. The Power5 will be the subject of the "Hot Chips" conference at Stanford this week. CBROnline provides some early details of the processor.

New features mentioned include more efficient "best in the industry" simultaneous multithreading (SMT), main memory controller on-chip, and dynamic power management. Initial Power5's are expected to use a 130-nm process with initial clock speeds between 1.5-2GHz.

While the Power5 may not find its way into Apple-branded machines, there have been rumors of Power5-based processors being developed that may be the successor to the PowerPC 970.
