Overview
- AWS says Graviton5 delivers up to 25% higher performance than Graviton4 while using less energy, though these figures are company-reported and await independent validation.
- Each chip features 192 cores, up from 96 in the prior generation, alongside larger caches and higher network and storage bandwidth to improve real-world workloads.
- A new Nitro Isolation Engine adds a formally verified, Rust-built layer to strengthen guarantees that tenant workloads remain isolated.
- EC2 M9g instances powered by Graviton5 are now in preview, with design improvements aimed at big data tools, gaming, and real-time online services.
- The launch aligns with hyperscalers’ push into custom silicon and intensifies competition with Intel and AMD, as analysts project roughly 23%–25% AWS growth in 2026 even as Amazon’s shares were down about 1.6% at publication.
