Xeon D-2177NT is a 64-bit 14-core high-performance x86 server microprocessor introduced by Intel in early 2018 for the dense server and edge computing market segment. Fabricated on Intel's 14 nm process based on the Skylake microarchitecture, this model operates at 1.9 GHz with a Turbo Boost of up to 3.0 GHz and a TDP of 105 W. The D-2177NT supports up to 512 GiB of quad-chanel DDR4-2666 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.
