  • ARM64

    ARM64 is the 64-bit Arm instruction set architecture, formally AArch64, used in processors from smartphones and laptops to cloud servers.

  • Cache

    A CPU cache is small, very fast memory inside the processor that keeps recently used data and instructions close to the cores to avoid slow RAM…

  • Clock speed

    Clock speed is the frequency, measured in gigahertz, at which a processor's clock signal advances its circuits through instruction cycles.

  • CPU

    A CPU, or central processing unit, is the general-purpose processor that fetches, decodes and executes the instructions of every program on a computer.

  • CPU core

    A CPU core is an independent processing unit within a processor that fetches, decodes and executes instructions, with its own registers and pipeline.

  • CPU thread

    A CPU thread is a hardware execution context that lets a processor core run an independent instruction stream, often two per core through SMT.

  • x86-64

    x86-64 is the 64-bit extension of the x86 instruction set architecture that runs most desktop, laptop and server processors in use today.
