Opteron A1170 is a 64-bit octa-core ARMv8 server microprocessor introduced by AMD in early 2016. This SoC is based on the Cortex-A57 microarchitecture and was fabricated on a GlobalFoundries 28 nm process. The A1170 has a TDP of 32 W with a core frequency of 2 GHz. It supports up to 128 GiB of dual channel DDR4-1866 memory.

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.
