Template:mpu Xeon Platinum 8156 is a 64-bit quad-core x86 multi-socket highest performance server microprocessor introduced by Intel in mid-2017. This chip supports up to 8-way multiprocessing. The Platinum 8156, 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 3.6 GHz with a TDP of 105 W and a turbo boost frequency of up to 3.7 GHz, supports up 768 GiB of hexa-channel DDR4-2666 ECC memory.
Cache
- Main article: Skylake § Cache
The Xeon Platinum 8156 features a considerably larger non-default 16.5 MiB of L3, a size that would normally be found on a 12-core part.

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. |
