Xeon Silver 4208 is a 64-bit octa-core x86 mid-range performance server microprocessor introduced by Intel in early 2019. The Silver 4208 is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm process. This chip supports dual-way multiprocessing, sports one AVX-512 FMA units as well as two UPI links. This microprocessor supports up 1 TiB of hexa-channel DDR4-2400 memory, operates at 2.1 GHz with a TDP of 85 W and features a turbo boost frequency of up to 3.2 GHz.

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.
