Suggested Approach

Start by defining the scope and assumptions of the TCO model, including hardware, software, energy, and operational costs. Then, quantify the performance and efficiency gains of GPU infrastructure over CPU alternatives, and translate those gains into revenue impact through metrics like time-to-insight, model accuracy, and scalability. Finally, connect the cost savings and revenue uplift to a compelling business case.

Pro tip: Emphasize that TCO is not just about cost reduction but about enabling new revenue streams and competitive advantages that CPUs cannot support. Use concrete examples, such as reduced training time leading to faster iteration and higher model accuracy, which directly impacts customer retention and upsell opportunities.

1. Define Scope and Assumptions

Clearly outline what is included in the TCO model (e.g., hardware acquisition, software licenses, power, cooling, maintenance, personnel) and the time horizon. State assumptions about utilization rates, workload characteristics, and depreciation.

2. Quantify Costs for GPU vs. CPU

Calculate total costs for both GPU and CPU infrastructure over the chosen period. Include capital expenditures (CapEx) and operational expenditures (OpEx), and consider factors like performance per dollar and energy efficiency.

3. Measure Performance and Productivity Gains

Benchmark key workloads (e.g., model training, inference) to quantify speedups, throughput improvements, and resource utilization. Translate these into productivity metrics such as reduced time-to-market or increased experiments per researcher.

4. Link Performance to Revenue Impact

Connect performance gains to revenue drivers: faster model deployment can increase customer satisfaction, enable new products, or improve sales conversion. Use metrics like revenue per inference, cost per prediction, or incremental revenue from faster insights.

5. Synthesize into a Business Case

Combine cost savings and revenue uplift to show net benefit. Present ROI, payback period, and sensitivity analysis. Highlight strategic advantages like scalability and future-proofing.

Key Points to Mention

  • Total Cost of Ownership components: CapEx, OpEx, energy, cooling, maintenance, software, personnel
