Evidence
Trainium3 NL32x2 Switched is also the only SKU with a switched scale-up architecture that can be deployed in datacenters that are not liquid cooled ready.
Context After
The use of air cooling provides a time to market advantage over other competitors’ liquid cooled scale-up switched accelerators since liquid cooled data center readiness is a key bottleneck of deployment currently. When operators try to force liquid cooled racks into an air-cooled datacenter, they must use an inefficient Liquid to Air sidecar. As such, we expect the majority of the Trainium3 chips deployed in 2026 to be in the form of the Trainium3 NL32x2 Switched SKU.
