I think the best way to determine the speed of an Intel
processor on a computer running Windows is to download,
install, and run the "Intel® Processor Frequency ID Utility"
from Intel's website.

http://support.intel.com/support/processors/tools/frequencyid/sb/CS-007623.htm

This utility will identify the speed of your processor, it's
CPUID classification, and your system bus frequency. You have
to remember that your processor runs at a fixed multiple of
your system bus frequency. My processor is identified as a
"PIII-1400 running on a 133 MHz system bus" when my system bus
is set to run at 133. (I can change the system bus frequency
by jumper.) If I set the system bus to 100 MHz, the processor
is identified as "PIII-1050 running on a 100 MHz. system bus.

My PIII processor has a built in fixed multiplier of 10.5.
(1400 = 10.5 X 133 whereas 1050 = 10.5 X 100.)

The "Intel Processor Frequency ID Utility" is the "last word"
on this matter...unless your notebook can change the bus
frequency.

As David said, some notebooks will slow down the processor to
save battery life or if the processor heats up too much. That
may be what's causing confusion with programs like Belarc Advisor.

(I actually have a p[air of PIII-1400 in this machine and Intel's
Frequency ID Utility correctly identifies both of them.)
