It is because of the HyperThread feature in the Intel CPU.
Hyperthreading - Initially referred to as Simultaneous Multi-threading or
SMT) allows for a single physical processor to appear to the operating
system as two logical processors. The operating system doesn't know the
difference and feeds threads to each as if they were indeed separate
physical processors.)

FWIW, Intel does not recommend Windows 2000 as the operating system of
choice if you wish to use hyperthreading. (Need Windows XP (SP1) or Windows
2003).
