What's new?

Quad core i7 instead of dual core i7 in 15" and 17"

i5 processor in 13"

Thunderbolt 10Gbps integrated into DisplayPort connection

AMD/ATI Radeon graphics chips

Actually the older generation of core i7 were quad core too but had less cache than this generation.

  L2 Cache (per core):	256 KB
  L3 Cache:	4 MB

My i7 says 2 cores in Device Profiler but says 4 in Activity Monitor, fwiw.

Hyperthreading. 2 physical core, 4 logical.
