Skylake X

Kaby Lake X (KBL-X) is the name of the core for Intel's high-end desktop (HEDT) microprocessor line based on the Kaby Lake microarchitecture serving as a successor to Broadwell E and a contemporary to Skylake X. Kaby Lake X processors are fabricated on Intel's enhanced 14nm+ process and feature considerably higher base clock when compared to the the mainstream desktop series of Kaby Lake models.

Overview[edit]

Kaby Lake X based processors are a 2-chip solution - the microprocessor and the chipset. Kaby Lake X are Socket R4 and use the Lewisburg chipset (HUB).


Common Features[edit]

All Kaby Lake X processors have the following:

  • TDP: 112 W
  • Dual-channel Memory
    • Up to DDR4-2666
    • Up to 64 GiB
  • Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2)
  • Support Turbo Boost 2.0, VT-x, VT-d, SpeedStep, Software Guard (SGX), and Memory Protection (MPX)
