Xeon Platinum 9221 is a 56-core 64-bit high-performance x86 server microprocessor introduced by Intel in early 2019. The 9221 is based on the Cascade Lake microarchitecture and is fabricated on Intel's 14 nm process. It operates at 2.1 GHz with a TDP of 250 W and a turbo boost of up to 3.7 GHz. This processor supports up to twelve channels of DDR4-2933 memory.

This processor cannot be purchased independently and is only sold as part of Intel's S9200WK Compute Module.

Cache

[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.
