Xeon D-1548 is a 64-bit octa-core x86 microserver SoC introduced by Intel in late 2015. The D-1548 is based on the Broadwell microarchitecture and is fabricated on their 14 nm process. It operates at 2.0 GHz with a TDP of 45 W and a turbo frequency of 2.6 GHz. This processor supports up to 128 GiB of dual-channel DDR4-2400 memory.

Cache

Main article: Broadwell § 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.
