Xeon Silver 4215 is a 64-bit octa-core x86 dual-socket mid-range performance server microprocessor introduced by Intel in early 2019. The Silver 4215, 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 two Ultra Path Interconnect links. This microprocessor, which operates at 2.5 GHz with a TDP of ? W and a turbo boost frequency of up to 3.5 GHz, supports up ? GiB of hexa-channel DDR4-2400 ECC 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.

[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.
