Core X is a family of high-performance and high core count 64-bit x86 microprocessors introduced by Intel in mid-2017.

Overview

The Core X family was announced during Computex 2017. Core X is effectively a successor to the Core i7 Extreme Edition family which used to feature Intel's flagship model from each architecture. The Core X family has expanded into a series of models ranging from 6 to 18 cores.

Skylake-based Core X processors were introduced at Computex 2017. Those processors incorporate a large number of changes over their Broadwell counterparts which brings along a performance increase in addition to other improvements. Those processors are also the first to incorporate the new AVX-512 extension. All models have the following common features:

TDP: 140, 165 W
Mem: Up to 128 GiB of quad-channel DDR4-2666
I/O: x44 PCIe Gen 3
ISA: Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2, and AVX-512)
Tech: Turbo Boost 2.0, Turbo Max 3.0, VT-x, VT-d, and SpeedStep

Kaby Lake

Kaby Lake-based Core X processors were introduced at Computex 2017 at the same time as the Skylake models. Despite that, those processors are far more similar to the high-end Core i7 (Kaby Lake S core) contemporaries in terms of features and capabilities vs the Skylake Core X variants. Likewise, they do not incorporate some of the more significant features such as a high core count, the cache hierarchy, and AVX-512. Additionally, those processors only support dual-channel memory.

TDP: 112 W
Mem: Up to 64 GiB of dual-channel DDR-2666 memory
I/O: x16 PCIe Gen 3
ISA: Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2)
Tech: Turbo Boost 2.0, Turbo Max 3.0, VT-x, VT-d, and SpeedStep

Skylake Refresh

See also: Skylake X Refresh

In late 2018 Intel refreshed the entire Skylake X lineup. In addition to the higher clock frequencies achieved as a result of utilizing their mature 14 nm process, those processors also makes use of solder thermal interface material instead of a paste, increasing the thermal conductivity and improving the available overclocking headroom. The refreshed lineup got rid of the hexa-core part and eliminates the PCIe lanes-based segmentation, providing x44 PCIe lanes on all models. Additionally, all models under 12 cores come with a larger L3 cache. Most of the low All models have the following common features:

TDP: 165 W
Mem: Up to 128 GiB of quad-channel DDR4-2666
I/O: x44 PCIe Gen 3
ISA: Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2, and AVX-512)
Tech: Turbo Boost 2.0, Turbo Max 3.0, VT-x, VT-d, and SpeedStep
