Skylake X Cascade Lake X

Skylake X Refresh is the processor core for Intel's high-end desktop (HEDT) microprocessor line based on the Skylake microarchitecture serving as a refresh to Skylake X. Those processors are fabricated on their 3rd generation 14nm++ process, bringing higher frequencies accross the entire lineup.

Overview

Skylake X Refresh 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 Refresh processors have the following:

• Quad-channel Memory
  • Up to DDR4-2400 / DDR4-2666
  • Up to 128 GiB
• x44 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)
