'''AWS Graviton''' ('''Alpine AL73400''') is a [[16-core]] [[ARMv8]] SoC designed by Amazon ([[Annapurna Labs]]) for Amazon's own infrastructure. The chip was first unveild by Peter DeSantis during Amazon's AWS re:Invent 2018. These processors are offered as part of Amazon's EC2 A1 instances. The Graviton features 16 {{armh|Cortex-A72|l=arch}} cores organized as four quad-core clusters, all operating at 2.3 GHz.
