Intel on Tuesday said it will ship a server chip that contains up to eight processing cores later this year, while IBM showed off a high-end server in the works that uses eight such chips, yielding 64 cores.
Using threads, Intel essentially doubles the amount of work that can be done on each processing core.
IBM, which participated in the conference, discussed a server currently under development that uses 64 Nehalem-EX cores (eight processors) and can handle 128 threads, according to Alex Yost, vice president IBM BladeCenter. "We're very excited today to be the first to demonstrate Nehalem-EX," Yost said.
Nehalem-EX will also double the memory capacity with up to 16 memory slots per processor socket, and offer four high-bandwidth "QuickPath" Interconnect links.
Intel also said the currently-shipping Nehalem server chip is making market gains. Intel's currently-available Xeon 5500, the first server processor based on Intel's Nehalem architecture, will be "greater than half of shipments" for Intel's high-volume two-processor (aka, "two-socket") server shipments by August, according to Davis.
The 4-core Xeons do the same thing. When you use "menumeters" on an 8 core Mac Pro, 16 core readings show up in your menu bar, pretty much taking up the entire space. So OS X sees 16 virtual cores. I'm interested to see how Snow Leopard deals with 32 threads on next years Mac Pro. I know this is an article about IBM and Intel, but Apple ends up using the a lot of the same technologies for their Mac Pro.
