Graviton5 M9g/M9gd GA: 192‑core ARM CPUs, DDR5‑8800, Nitro Isolation
AWS now offers M9g and M9gd instances powered by Graviton5, a 192‑core ARM processor with a five‑times larger L3 cache, up to 33 % lower inter‑core latency, DDR5‑8800 memory and formally verified Nitro Isolation Engine. Early tests show 35‑60 % performance gains for databases and AI agents, while isolation guarantees VM security. The GA launch gives developers a compute platform for demanding workloads.
