Opteron A1120 is a 64-bit quad-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 A1120 has a TDP of 25 W with a core frequency of 1.7 GHz. It supports up to 128 GiB of dual channel DDR4-1866 memory.

Cache[edit]

[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.
