Xeon Platinum 8260 is a 64-bit24-corex86 multi-socket highest performance server microprocessor expected to be introduced by Intel in late 2018. This chip supports up to 8-way multiprocessing. The Platinum 8260, which is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm++ process, sports 2 AVX-512FMA units as well as three Ultra Path Interconnect links. This microprocessor, which operates at 2.3 GHz with a TDP of 165 W and a turbo boost frequency of up to 3.9 GHz, supports up ? GiB of hexa-channel DDR4-2666 memory.
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.
