AWS Graviton4 (Alpine ALC14C00) is a hexanonaconta-core ARMv9 multiprocessor designed by Amazon (Annapurna Labs) for Amazon's own infrastructure. Graviton4 is a 5 nm(?) 7-chiplet design SoC based on the Arm CMN-700 mesh interconnect and Neoverse V2 core microarchitecture. This chip supports dodeca-channel DDR5-5600 ECC memory.
This 4th-generation server processor was first announced during Amazon's AWS re:Invent 2023 by Adam Selipsky in his keynote. The general rollout for the Graviton4 chip in the AWS data center took place in early 2024. These processors are offered as part of Amazon's EC2 instances.
