Context Before
While Trainium2 will only be available in the first two rack SKU types – namely the Trn2 NL16 2D Torus and Trn2 NL32x2 2D Torus servers, Trainium3 will be offered in all four rack SKU types, with the majority of Trainium3 delivered in the Trainium3 NL32x2 Switched SKU in 2026. We expect that most of the Trainium3 to be deployed in the Trainium3 NL32x2 Switched and Trainium3 NL72x2 Switched SKUs during its lifecycle.
