'''AWS Graviton3''' is a [[tetrahexaconta-core]] [[ARMv8]] microprocessor designed by [[Amazon]] ([[Annapurna Labs]]) for Amazon's own infrastructure. Graviton3 is a [[5 nm]] 7-chiplet design SoC based on the Arm [[CMN-650 mesh interconnect]] and [[Neoverse V1]] core microarchitecture. This chip supports octa-channel DDR5-4800 ECC memory along with 32 lanes of PCIe 5.0.

== Overview ==
This 3rd-generation server processor was first announced during Amazon's AWS re:Invent [[2021]]. The general rollout for the Graviton3 chip in the AWS data center occurred in early 2022. These processors are offered as part of Amazon's EC2 instances.
