Saying it has 7 is misleading in the same way as if i told you now: "look, i have four eyes!". (they are: left eye looking right, left eye looking left, right eye looking left and right eye looking right) Nehalem has 4 general purpose PMCs, not 7. Yes, it has 7 counters but they are not all general purpose. The P4 has 18.
