Xeon Gold 5220 is a 64-bit octadeca-core x86 multi-socket high performance server microprocessor exected to be introduced by Intel in late 2018. This chip supports up to 4-way multiprocessing. The Gold 5220, which is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm++ process, sports 1 AVX-512 FMA unit as well as three Ultra Path Interconnect links. This microprocessor, which operates at 2.2 GHz with a TDP of ? W and a turbo boost frequency of up to 3.9 GHz, supports up ? GiB of hexa-channel DDR4-? memory.

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

Main article: Cascade Lake § Cache

[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.
