An interesting question. AFAIK there is no general purpose way to get this out of the CPU, am I wrong on this? I figure you have to at least talk to the chipset and get some info ...

Minnich <rminnich@lanl.gov> Subject: Actual/operating CPU frequency Hi Ron, Would you happen to have any source around (assembly is fine) that will return the actual clock speed that a processor (Intel and AMD) is running at? I have the start of some code but I'm having a tough time getting the details worked out. I know the BIOS has a 'ticker' with a known speed so I could then use the time step counter to eventually get to the cpu frequency but but I haven't found out exactly how to do this in several attempts. Any ideas? This code will eventually have to run under both Linux and Windows (ugh).
