KaiXian KX-5640 is a 64-bit quad-core x86 microprocessor designed by Zhaoxin and introduced in late 2017 specifically for the Chinese market. This processor is fabricated on a 28 nm process based on the WuDaoKou microarchitecture. The KX-5640 operates at 2 GHz with a TDP of ? W and supports up to 64 GiB of dual-channel DDR4-2133 memory. The KX-5640 also incorporates an integrated graphics processor.

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.
