Well, the Pentium-M is better at the same clock rate than the P4. Centrino
is _not_ a CPU, Centrino is the name for the combination of Pentium-M CPU,
intel chipset and intel WLAN...

Don't know if it is twice
the performance though. For some tasks, it might be!

A rough estimation is that a P-M is ~1.6x the performance of a P4 with same
clock speed. That means a P-M 1.5GHz is _around_ the same performance than a
P4 2.4GHz. For some applications (i.e. floating point) and for most games
the P4 is faster.
