Apple's Mac Pro has an undocumented feature: it runs eight physical processors without breaking a sweat
My former boss Anand Shimpi arguably has the best hack all
week. Shimpi managed to get his Mac Pro to recognize two quad-core
Clovertown processors (running at 2.4GHz per core) in a single Mac Pro -- the resulting system ran
flawlessly on eight processor cores.
No BIOS updates, no pin-hacks or anything exotic was needed to get the yet unannounced
processors to work in the Mac Pro. Shimpi adds "We
can't say with 100% certainty that you will be able to upgrade to Clovertown
when it comes out, but so far the results are looking good."
The Mac Pro is unique in the fact that the system uses server processors as
opposed to desktop processors. The Socket 771 Xeons used in existing
Mac Pros, dubbed
Woodcrest, support FB-DIMM memory -- the desktop variants do not.
Intel has publically announced
several times that quad-core desktop and server processors would be
shipping from the company before the end of the year. The desktop
versions of the processors, dubbed Kentsfield, will carry the Core 2 Extreme
brand. The server brand, codenamed Clovertown,
has not been announced yet.
The Kentsfield desktop quad-core processor is expected to
launch at a steep $999 MSRP, and typically server components from Intel MSRP
for about 20% more than the desktop variants.
