Finding out the CPU clock frequency (per core, per processor)

Question

Programs like CPUz are very good at giving in depth information about the system (bus speed, memory timings, etc.)

However, is there a programmatic way of calculatin

Answer 1

You need to use CallNtPowerInformation. Here's a code sample from putil project. With this you can get current and max CPU frequency. As far as I know it's not possible to get per-CPU frequency.
