AWS Graviton5 Reaches General Availability with 192 Cores and Formally Verified VM Isolation
Why it matters
AWS's custom silicon is closing the performance gap with mainstream CPUs while improving unit economics for AI/ML workloads. This directly impacts infrastructure capex decisions for any org running compute-intensive AI at scale.
Key signals
- AWS Graviton5: 192 ARM cores, DDR5-8800 memory
- ClickHouse reports 36% performance improvement with zero code changes
- Meta committed tens of millions of cores to Graviton5
- 9% price premium over Graviton4 translates to ~15% better price-performance
- Formally verified VM isolation via Nitro Isolation Engine
- M9g and M9gd EC2 instances now generally available
The hook
192 cores. AWS Graviton5 just went GA with 15% better price-performance than Graviton4—and Meta already committed tens of millions of cores.
AWS made Graviton5-powered EC2 M9g and M9gd instances generally available with 192 ARM cores, formally verified VM isolation via the Nitro Isolation Engine, and DDR5-8800 memory. ClickHouse reported 36% better performance with zero code changes. Meta committed tens of millions of cores. On-demand pricing is 9% above Graviton4, translating to roughly 15% better price-performance.
