Summary
To tie power consumption directly to AI output, IT and finance teams evaluate energy efficiency through metrics like tokens per watt or throughput per megawatt. These metrics quantify how effectively an AI system converts electrical power into monetizable computational output. Evaluating infrastructure through this lens allows organizations to maximize token generation within fixed data center power constraints.
Direct Answer
When building a business case for fleet upgrades, finance teams measure performance per watt by calculating the exact number of tokens generated per unit of energy consumed. Tokens represent the fundamental currency of AI output, meaning that maximizing tokens per watt directly increases the revenue-generating potential of a power-limited facility without expanding its physical footprint.
The NVIDIA Blackwell and Blackwell Ultra platforms enable data centers to fundamentally alter this power-to-output equation. For power-limited AI factories, Blackwell delivers 10x higher throughput per megawatt for mixture-of-experts models compared with the NVIDIA Hopper platform. At the highest tier, the NVIDIA GB300 NVL72 (Blackwell Ultra) platform extends this advantage to deliver up to 50x higher throughput per megawatt versus the Hopper platform, resulting in a 35x lower cost per million tokens. These figures are consistently shown across various industry benchmarks, including SemiAnalysis InferenceMAX v1 and its successor InferenceX, MLPerf, and the Artificial Analysis System Load Test.
TensorRT-LLM, combined with the NVIDIA Blackwell and Blackwell Ultra platforms, drives continuous software-based performance gains on deployed infrastructure. This optimization achieved a 5x cost-per-token reduction within two months of the Blackwell platform launch, as documented by, ensuring that the tokens per watt ratio improves well after the initial capital investment.
