Xeon Gold 5220T is a 64-bit 18-core x86 high performance server microprocessor introduced by Intel in early 2019. The Gold 5220T is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm process. This chip supports 4-way multiprocessing, sports one AVX-512 FMA units as well as three UPI links. This microprocessor supports up 1 TiB of hexa-channel DDR4-2666 memory, operates at 1.9 GHz with a TDP of 105 W and features a turbo boost frequency of up to 3.9 GHz.

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.
