Unit
x higher output tokens per megawatt at similar latency per user (vendor claim)
Model
unspecified (vendor claim, workload not stated)
Methodology
VENDOR CLAIM (AWS What's New, Trn3 UltraServer GA, Dec 2 2025). 'On Amazon Bedrock, Trainium3 is our fastest accelerator, delivering... over 5x higher output tokens per megawatt at similar latency per user' vs Trainium2. Energy-normalized throughput ratio, not a speedup.

vendor
Reproducible
no
notes
Filed as dimensionless_ratio (not speedup_ratio) because it is a throughput-per-watt figure, not a faster/slower time ratio. The only energy-normalized number for the part.
