Abstract: Organizations deploying AI inference systems for knowledge-work automation currently lack a shared, intuitive vocabulary for capacity planning and procurement. Existing metrics — tokens per second, FLOPS, benchmark scores — carry precise technical meaning but fail to communicate operational impact to the managers and executives who make infrastructure investment decisions. This paper introduces a dual-metric framework that addresses this gap. The first metric, Desk Power (DP), quantifies the economic replacement capacity of an AI server in terms of equivalent human office workers, drawing explicit analogy to James Watt's mechanical horsepower. The second metric, Concurrent Human-Speed Workflows (CHW), quantifies the number of simultaneous users or workflow streams a given system can serve at or above a specified responsiveness threshold. Together, DP and CHW answer the two questions that drive real procurement decisions: how many employees can this system replace (DP), and how many employees can it serve at once (CHW). A formal mathematical framework is developed for both metrics, incorporating token generation rate, system availability, parallelism, quality correction, and response-speed thresholds. Worked examples are provided for systems ranging from local consumer-GPU edge nodes to enterprise multi-GPU clusters. The proposed framework offers a vendor-neutral, audience-appropriate language for AI capacity planning, workforce transition analysis, and regulatory impact assessment.
