E6420 As-Built VS Current Configuration QUESTION

I just received an E6420 billed as an i7-2720QM, 4 Core CPU.  I'm almost certain that when I viewed the BIOS it also identified as such.  

I upgraded the BIOS from A01 to A05, and then form A05 to A24.  Now, the machines current configuration identifies the CPU as an i7-2640M 2 core CPU, but with a -4 appendix, as if the machine knows it has 4 cores.  I would like to know once and for all what I actually have without disassembly.
