Kunpeng 916 (Hi1616) is a dotriaconta-core64-bitARM server microprocessor introduced by HiSilicon in mid-2017. Fabricated by TSMC on a 16 nm process, this chip incorporates 32 Cortex-A72 cores operating at 2.4 GHz with a TDP of 85 W. The Hi1616 supports up to 512 GiB of quad-channel DDR4-2400 memory. This chip supports up to 2-way SMP with two ports supporting 96 Gb/s each.
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.
