AWS Graviton5 doubles core count to 192, introduces formally verified Nitro Isolation Engine for enterprise AI workloads
By

Summary
Amazon Web Services has released Graviton5, its fifth-generation custom CPU, now generally available on EC2 M9g instances. The chip doubles core count from 96 to 192, moves to TSMC's 3nm process, and introduces the Nitro Isolation Engine — the first formally verified (mathematically proven) cloud hypervisor. M9g instances deliver up to 25% higher compute performance than Graviton4-based instances. The article discusses how these architectural changes impact enterprise planning for agentic AI workloads and cloud infrastructure strategy.

· 3 pulledGraviton5 doubles core count from Graviton4's 96 to 192, moves to TSMC's 3nm process, and ships alongside the Nitro Isolation Engine, a hypervisor whose security properties are established through mathematical proof rather than audit.
M9g instances deliver up to 25% higher compute performance than Graviton4-based instances.
For enterprises planning agentic AI infrastructure, both developments affect how they should evaluate AWS compute going forward.
