W-3225 is a 64-bit octa-core x86 enterprise performance workstation microprocessor introduced by Intel in 2019. This processor is fabricated on an enhanced 14nm++ process based on the Cascade Lake microarchitecture. The W-3225 operates at 3.7 GHz with a TDP of 160 W, a turbo boost frequency of up to 4.3 GHz and a turbo boost max of 4.4 GHz. This chip supports up to 1 TiB of hexa-channel DDR4-2666 memory.

Cache

Main article: Cascade Lake § Cache

This processor has a non-default level 3 cache of 16.5 MiB, an amount usually found in the 12 cores part.

[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.
