Xeon Platinum 8276M is a 64-bit 28-core x86 multi-socket highest performance server microprocessor planned by Intel for late 2018. This chip supports up to 8-way multiprocessing. The Platinum 8276M, which is based on the Cascade Lake 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 2.2 GHz with a TDP of 165 W and a turbo boost frequency of up to 4 GHz, supports up ? TiB of hexa-channel DDR4-2666 memory.

As indicated by the M suffix, this specific model supports double the memory capacity for up to ? TiB per socket.

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.
