Skylake X (SKL-X) is the processor core for Intel's high-end desktop (HEDT) microprocessor line based on the Skylake microarchitecture serving as a successor to Broadwell E. Skylake X processors feature a large array of enhancements and improvements including the new AVX-512 extension. Unlike the mainstream Skylake processors, enthusiasts Skylake X models are fabricated on Intel's enhanced 14+ nm process.

Overview

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

Common Features

All Skylake X processors have the following:

Quad-channel Memory
- Up to DDR4-2400 / DDR4-2666
- Up to 128 GiB
28x or 44x PCIe
6 cores to 18 cores with all models supporting Hyper-Threading)
Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, AVX2, and AVX-512)
