Amazon AWS today announced Graviton5 as their newest-generation ARM64 server processor for their EC2 cloud. Graviton5 is being promoted as offering 25% higher performance over existing Graviton4 processors.

Graviton5 will offer up to 192 cores per chip, 5x larger L3 cache, and "leading" energy efficiency. Graviton5 EC2 servers will also feature up to 15% higher network bandwidth and up to 20% higher Amazon Elastic Block Store bandwidth.

Technical details beyond those key points were light in today's Graviton5 announcement. Amazon says Graviton5 will be found in the M9g instance type for general purpose workloads currently in preview form. There will be C9g for compute-intensive workloads with Graviton5 as well as R9g for memory-intensive workloads but not available until 2026.

More details can be found via today's [1]AWS announcement for Graviton5. I will be running some AWS Graviton5 CPU benchmarks at Phoronix as soon as I have access on EC2 to the Graviton5 instance types.
