Amazon Web Services has announced Graviton5, the fifth generation of its custom ARM-based processor for EC2, at a virtual event today.
40% Faster per vCPU
Built on ARM Neoverse V3 cores on TSMC's 3nm process, Graviton5 delivers roughly 40% higher integer performance and 50% higher floating-point performance per vCPU compared to Graviton4, based on AWS's SPEC CPU 2017 measurements.
New Instance Families
M8g, C8g, R8g, and X8g instance families launch today in us-east-1 and eu-west-1, with other regions rolling out through Q2. Maximum instance size is 192 vCPUs and 1.5 TB RAM, up from 128/1 TB on Graviton4.
Confidential Computing GA
Graviton5 includes Arm CCA (Confidential Compute Architecture) support, and new *g.metal bare-metal instances expose it to customers. Nitro Enclaves built on CCA enable hardware-isolated trusted execution environments with attestation.
