Xeon Platinum 8124 is a 64-bit 18-core x86 multi-socket highest performance server microprocessor introduced by Intel in 2017. This chip supports up to 8-way multiprocessing. The Platinum 8124, which is based on the server configuration of the Skylake microarchitecture and is manufactured on a 14 nm+ process, sports 2 AVX-512 FMA units as well as three Ultra Path Interconnect links. This microprocessor, which operates at 3 GHz with a TDP of 240 W and a turbo boost frequency of up to 3.4 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.

This specific model appears to be a custom model only for Amazon AWS.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

Cache[edit]

[Edit/Modify Cache Info]

Cache Organization

Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
