Kunpeng 920 (Hi1620) is a planned octatetraconta-core 64-bit ARM server microprocessor set to be introduced by HiSilicon in late-2018. Fabricated by TSMC on a 7 nm process, this chip incorporates 64 custom cores operating at 2.4-3 GHz with a TDP of up to 200 W. The Hi1620 supports up to 1 TiB of octa-channel DDR4-3200 memory.

[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.
