    What does RDTSC mean?
    RDTSC measures the number of clock cycles that have elapsed on the processor that it is executed on. If your code is running on a multi-core processor, each core may have its own TSC, and the values may not be synchronized.

    Why do we use RDTSC?
    Does anyone know why? Its common to use RDTSC to get fine-grained timing information, where the overhead of a virtualization trap would be quite significant. Most common use is to have two RDTSC instructions with a small amount of code between them, taking the difference of the times as the elapsed time (number of cycles) for the code sequence.

    Why is RDTSC a virtualized instruction on modern processors?

    What is RDTSC in assembly language?
    In Assembly language, we can use the RDTSC instruction to measure the number of clock cycles that have elapsed since the processor was reset. This can be a very accurate way to measure time, but it requires some knowledge of how the processor works. What is RDTSC? RDTSC is an Assembly language instruction that stands for "Read Time-Stamp Counter".

    What is the RDTSC instruction?
    The RDTSC instruction is a 64-bit value, which contains the number of clock cycles that have elapsed and is accessible from the Application Ring meaning non-system software have access to it! Win32 hasn't blocked access so it is available for reading.
