AWS Graviton2 (Alpine ALC12B00) is a 64-core ARMv8 SoC designed by Amazon (Annapurna Labs) for Amazon's own infrastructure, serving as a successor to the original AWS Graviton. The chip was first unveiled during Amazon's AWS re:Invent 2019 and has been in deployment for user access since early 2020. These processors are offered as part of Amazon's EC2 M6g, C6g, and R6g instances. The Graviton 2 features 64 Neoverse N1 on a mesh, all operating at 2.5 GHz.

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. |
