perchè alcune CPU quad di Intel implementano anche la funzione Hyperthreading:

Processore Intel I7 quad-core @2.8GHz:

1 HT-enabled Quad core processor shows 8 processors in Red Hat, so 2 should
show 16 processors.
Unless the kernel (for commercial reasons) has not been enabled to see them.
Don't forget to check in the BIOS if Hyper Threading is enabled.
I checked on a Intel Core i7 920 system : both Fedora 14 x86_64 and CentOS 5
x86_64 display 8 processors (from 0 to 7) in /proc/cpuinfo .
