Template:mpu Xeon Silver 4109T is a 64-bit octa-core x86 dual-socket mid-range performance server microprocessor introduced by Intel in mid-2017. The Silver 4109T, which is based on the server configuration of the Skylake 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 GHz with a TDP of 70 W and a turbo boost frequency of up to 3 GHz, supports up 768 GiB of hexa-channel DDR4-2400 ECC memory.

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.
