Intel provides numerous micro-architectures and CPUs. This article gives an overview about them.

Intel Tick-Tock Development Model

Intel develops new micro-architectures according to the Tick-Tock model:[1][2]

  • shrinking of process technology of the previous micro-architecture (Tick)
  • new micro-architecture (Tock)
