Kunpeng 920-4826 is a octatetraconta-core 64-bit ARM server microprocessor introduced by HiSilicon in early 2019. Fabricated by TSMC on a 7nm HPC process based on the TaiSHan v110 microarchitecture, this chip incorporates 48 cores operating at 2.6 GHz with a TDP of 150 W. This chip supports up to 1 TiB of octa-channel DDR4-2933 memory.

Cache[edit]

Main article: TaiShan v110 § 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.
