This is very prevalent in the market - PPM is present on nearly every commodity processor shipped today (with the exception of some “low-power” processor SKUs), and Windows ships with PPM Luckily xperf tracing can now show this disparity. However, the CPU core number can be calculated more easily using binary numbers.

For example, a processor that supports Intel’s Hyper-Threading technology will have two logical cores per physical core. Make sure Windows => Keep CPU Windows on Top is disabled (unchecked).
