Which exact processor model do the macbook pros have? The new 15 and 17 inch macbook pros only list the processor model as quad-core core i7.
However what is the fully model number of the processor?
Are the quad core processors really dual cores with hyperthreading or are they really quad core? 
Do any of the models have hyperthreading?

As requested pasting info about the macbook pro model to enhance this page:

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.
