ThunderX2 CN9970 is a 64-bit tetracosa-core high-performance ARM server microprocessor introduced by Cavium in mid-2018. The microprocessor, which is based on the Vulcan microarchitecture, is fabricated on TSMC's 16 nm process. Depending on the exact SKU, the CN9970 operates between 1.8 GHz and 2.5 GHz and supports up to quad-/hexa/octa-channel DDR4-2666 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.
