W-3175X is a 64-bit 28-core x86 enterprise performance workstation microprocessor introduced by Intel in early 2019. This processor is fabricated on an enhanced 14nm++ process based on the Skylake server microarchitecture, operates at 3.1 GHz with a TDP of 255 W and a turbo boost frequency of up to 4.3 GHz. This chip supports up to 512 GiB of hexa-channel DDR4-2666 ECC memory.

The Xeon W-3175X is the only Xeon with a multiplier unlocked for overclocking.

Cache[edit]

[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.
