Template:mpu Xeon Platinum 8168 is a 64-bit x86 high-performance server tetracosa-core multiprocessor set to be introduced by Intel in the second quarter of 2017. This processor is based on the server configuration of the Skylake microarchitecture (a Skylake SP core) and is manufactured on Intel's 14 nm process. The 8168 operates at 2.7 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.
