MacBookPro Core i7 - system profiler says “Number of cores: 2”

Question

I thought that "quad core" meant quad core. My system says that it has 2 cores, but perhaps I'm thinking of it wrong, or perhaps the OS ignores 2 cores. What do you know about the issue.

(Note: Intel isn't shipping the new dual core i5 / i7s until the 20th, so if mine actually is a "dual core", I'm gonna be mad).

Profiler output:

Model Name: MacBook Pro
  Model Identifier: MacBookPro6,2
  Processor Name:   Intel Core i7

Answer 1

You have the Intel i7 M620 with 2 cores. Mactracker confirms CPU model (i7 M620) for your device.

Apple doesn't advertise number of cores in tech specs, but the store clearly says:

Intel didn't offer models with 2+ GHz and 4 cores until 2011.
