IBM Gives Details on Octo-Core Power7 Processor

The CPU wars in the desktop market have grown pretty stale with Intel's Core i7 architecture kicking AMD's tail, but when it comes to the server sector, the battle is starting to heat up.

Enter IBM, who at this week's Hot Chips conference officially unveiled its muscular 8-core Power7 processor. The mighty chip is expected to pack 1.2 billion transistors onto a 45nm die. Each core will boast 12 execution units, as well as 32 threads per chip and advanced pre-fetching data and instruction sets.

"I am sure Power7 will be the fastest processor around, probably faster than Intel's Nehalem in some benchmarks," said Nathan Brookwood , principal of market watcher Insight64.

Other specs include scalability up to 32 sockets, 256KB L2 cache per core, 32MB of on chip eDRAM shared L3 cache, dual DDR3 memory controllers, 100GB/s memory bandwidth per chip, and 360GB/s SMP bandwidth per chip.
