new Mac Pro supports up to 12 cores. Twelve!
So now you can have a 12-core system at up to 2.93GHz and the Intel Xeon processors support Hyper-Threading, which allows two threads to run simultaneously on each core. So, for example, a 12-core Mac Pro presents 24 virtual cores that are recognized by Mac OS X.
Not only will it have incredible processing power but it allows up to 32BG RAM and up to 8TB storage (or four 512GB Solid-State drives). I think I'm in love... again.
