AWS Trainium3
The 3-nanometer follow-on, previewed for 2026 UltraServers.
You're looking at a chip record: what this processor is, its key specs, who designs, manufactures and supplies its parts, and where it gets used.
AWS previewed Trainium3 at re:Invent 2024 as its first 3 nm-class chip, targeting several times Trainium2 UltraServer performance at better efficiency, with first deployments from late 2025 into 2026. Figures are company targets until instances are generally available.
Specifications & key facts
Each figure is labeled by basis: vendor spec, vendor claim, reported, estimate, or official. "Not publicly disclosed" means exactly that — we never invent values.
