So the Number of Hardware Counters on what we see above is 11 per core. Webperformance counters, selected with bit 31 of the ECX register. If bit 31 is set, the RDPMC instruction reads only the low 32 bits of the selected performance counter; if bit 31 is clear, all 40 bits of the counter are read. A 32-bit read executes faster on a Pentium 4 or Intel Xeon processor than a full 40-bit read
