Xeon D-1543N is a 64-bit octa-core x86 microserver SoC introduced by Intel in late 2017. The D-1543N is based on the Broadwell microarchitecture and is fabricated on their 14 nm process. It operates at 1.9 GHz with a TDP of 45 W and a turbo frequency of 2.5 GHz. This processor supports up to 128 GiB of dual-channel DDR4-2400 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.
