Which are virtual cores on a Core i7?

[MarchTheMonth]

I know how I could test which cores are paired on the Core i7 (set affinity to each core and see which core heats up), but does anyone have a decisive list of which core is physical and which is virtual?

example:
Phys:Virt
0:1
2:3
etc

I believe that actual cores are listed first in the MPI spec tables in the BIOS. So Core0-3 are physical, core 4-7 are virtual.
