TDP
Power
DEFINITION
Thermal Design Power - The maximum amount of heat a GPU is designed to dissipate under typical workloads, measured in watts.
OVERVIEW
TDP (Thermal Design Power) indicates the maximum amount of power a GPU will consume under sustained load, which directly correlates to heat generation and cooling requirements.
TECHNICAL DETAILS
TDP is measured in watts and helps determine the cooling solution and power supply requirements. A higher TDP generally means more performance but also more heat and power consumption. Data center GPUs like the H100 can have TDPs of 700W, while consumer cards range from 150W to 450W. The actual power consumption can vary based on workload and power management settings.
COMMON USE CASES
- Sizing power supplies for GPU servers
- Planning data center cooling infrastructure
- Calculating operational costs for GPU clusters
- Determining rack power density limits
- Selecting appropriate cooling solutions
