Unfortunately it's a calculated value, so tends to be +- a few %. If the OP can actually find something that will give him spot on (aka what the user expects) speeds, I'd be very grateful if he would share it, I've been trying to solve this one on and off for months.

My tz-check.pas, written in Delphi 3, available via below, measures it; see the last paragraph of output, and where RDTSC appears in the source. The source is under 200 lines total, and the relevant part is easily located as above. If you want the exact "advertised" speed, you will have to (a) find the nearest in a table of values, (b) allow for Athlons, where IIRC the advertised speed is not the clock speed. -- © John Stockton, Surrey, UK. ?@merlyn.demon.co.uk Turnpike v4.00 MIME. © Web <URL:http://www.merlyn.demon.co.uk/> - w.

But it does allow Intel to charge a hefty premium for the notebook specialized CPU . The really nutty thing about reducing CPU speed is that it really only makes sense if the machine is idle, i.e. sitting in the o/s idle loop. When a user is working, reducing the speed may extend battery life, but its also going to extend the user's time to completion - and probably raise their level of frustration.

Is asking for "the" processor speed the next incarnation of asking for "the" IP address? Possibly, but maybe even worse... At least there is an answer to the IP question... Nobody as yet has found a way of getting a 3.06Ghz P4 to report 3.06 and a 3Ghz P4 to report 3Ghz. These two are a particular favourite of mine. Being only 2% apart is more than enough play for the registry ~Mhz value code to muddle them up when using a nearest fit routine. And let's not even venue into AMD land where the value expected by the user will have pitifully little to do with the Mhz of the chip!
