Please specify which generation; people may see this in the future when it isn't so clear. –  Brian Carlton Mar 18 '11 at 21:12

It's in System Profiler, on the first page that shows up on launch. –  CajunLuke Mar 19 '11 at 0:27

The processor used in the early 2011 15" and 17" i7 models is the 2.2 GHz quad-core (2720QM) Intel Core i7 Sandy Bridge with 6 MB on-chip L3 cache, so they have 4 cores and 8 threads.

Apple's MacBook Pro performance page makes it clear that Hyper-Threading is now standard on all MacBook Pro laptops.

I do not know the model number, but they are actually quad core with hyperthreading, giving 8 logical cores.
