    en.wikipedia.org/wiki/Clock_rate

    For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...

  4. Idle (CPU) - Wikipedia

    en.wikipedia.org/wiki/Idle_(CPU)

    Many operating systems, for example Windows, [1] Linux, [2] and macOS [3] will run an idle task, which is a special task loaded by the OS scheduler on a CPU when there is nothing for the CPU to do. The idle task can be hard-coded into the scheduler, or it can be implemented as a separate task with the lowest possible priority.

  6. FLAGS register - Wikipedia

    en.wikipedia.org/wiki/FLAGS_register

    The FLAGS register is the status register that contains the current state of an x86 CPU.The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time.

  7. x86-64 - Wikipedia

    en.wikipedia.org/wiki/X86-64

    AMD64 (also variously referred to by AMD in their literature and documentation as “AMD 64-bit Technology” and “AMD x86-64 Architecture”) was created as an alternative to the radically different IA-64 architecture designed by Intel and Hewlett-Packard, which was backward-incompatible with IA-32, the 32-bit version of the x86 architecture.

  8. SPECint - Wikipedia

    en.wikipedia.org/wiki/SPECint

    For SPECint2006, the CPUs include Intel and AMD x86 & x86-64 processors, Sun SPARC CPUs, IBM Power CPUs, and IA-64 CPUs. This range of capabilities, specifically in this case the number of CPUs, means that the SPEC INT benchmark is usually run on only a single CPU, even if the system has many CPUs.
