Over at CNET labs, they've done gone and stuck a couple of new Intel quad-core Xeon 5355 processors into an Apple Mac Pro and ran copious benchmarks
on their new baby. Surprisingly enough, a single 3.0 GHz quad core kicked the bejesus out of the 2.66 GHz oct cores in some of the tasks. Follow the link to see lots and lots of bar graphs.
And yes, that is 8 cores hard at work in the CPU monitor. How long will we have to wait until we can pick up this configuration from Apple, instead of having to hack our way to more cores?
