AWS Graviton (Alpine AL73400) is a 16-core ARMv8 SoC designed by Amazon (Annapurna Labs) for Amazon's own infrastructure. The chip was first unveiled by Peter DeSantis during Amazon's AWS re:Invent 2018 and has been in deployment for user access since early 2019. These processors are offered as part of Amazon's EC2 A1 instances. The Graviton features 16 Cortex-A72 cores organized as four quad-core clusters, all operating at 2.3 GHz.

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.
