Xeon Phi 7295 is a 72-core x86 many-core microprocessor introduced by Intel in late 2017 specifically designed to accelerate artificial intelligence workloads. This processor, which is fabricated on their own 14 nm process based on the Knights Mill microarchitecture, operates at a frequency of 1.5 GHz with a TDP of 320 W and a turbo of 1.6 GHz.

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.
