'''AWS Graviton 2''' ('''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 {{armh|Neoverse N1|l=arch}} on a mesh, all operating at 2.5 GHz.
