AWS Unveils Graviton5 and M9g Instances: More Power, Proven Isolation, and What It Means for the Cloud

AWS has announced Graviton5, its fifth-generation Arm-based processor, alongside a preview of new EC2 M9g instances. Delivering up to 25% higher performance than Graviton4, Graviton5 introduces a significantly larger L3 cache, higher memory and network bandwidth, and up to 192 CPU cores per instance. A major highlight is the new Nitro Isolation Engine, which uses formal verification to mathematically prove workload isolation—setting a new benchmark for cloud security. While adoption of Graviton continues to accelerate, early reactions note limited benchmarks and regional availability during preview.
