KaiXian KX-U5580M is a 64-bit octa-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-U5580M operates at 1.8 GHz with a TDP of ? W and supports up to 64 GiB of dual-channel DDR4-2133 memory. The KX-U5580M also incorporates an integrated graphics processor.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

Cache

Main article: WuDaoKou § 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.
