W-2145 is a 64-bit octa-core x86 enterprise performance workstation microprocessor introduced by Intel in 2017. This processors, which is fabricated on an enhanced 14nm+ process based on the Skylake server microarchitecture, operates at 3.7 GHz with a TDP of 140 W and a turbo boost frequency of up to 4.5 GHz. This chip supports up to 512 GiB of quad-channel DDR4-2666 ECC memory.

Cache

Main article: Skylake § 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.
