Cascade Lake AP (CLX-AP, Cascade Lake Advanced Performance) is code name for a series of high core-count multi-chip packaged server multiprocessors based on the Cascade Lake microarchitecture part of the Walker Pass platform.

Cascade Lake AP-based processors are branded as Xeon Platinum 9200-series.

Overview

Cascade Lake AP comprise of two Cascade Lake dies packaged together a single BGA-5903 substrate. Those processors support up to 56 cores, 112 threads, and up to 12 DDR4 channels.

Cascade Lake AP processors cannot be purchased individually. Instead, they can only be bought as part of the S9200WK compute module (essentially a complete system designed by Intel).

Common Features

• 12-channel memory
  • UP to DDR4-2933 MT/s
  • ECC support
• TDP: 250 W to 400 W
• PCIe: x40 Lanes of PCIe Gen 3 (limited by the S9200WK module, actual models support more lanes but are not sold independently)
• ISA: Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2, AVX512F, AVX512CD, AVX512BW, AVX512DQ, AVX512VL, AVX512VNNI)
• Features: Speed Shift, vPro, VT-x, TSX, TXT
