ThunderX2 CN9980 is a 64-bit dotriaconta-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 CN9980 operates between 2 GHz and 2.5 GHz and supports up to octa-channel DDR4-2666 memory.

Cache[edit]

[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.
