TDP · Thermal Design Power
A vendor-defined thermal/design rating used to size a product's power and cooling envelope. Its definition and test basis vary by product; TDP is not necessarily measured sustained electrical input, typical workload draw, or maximum/peak power.
Use the vendor's named product definition and test basis. Keep TDP separate from measured sustained input, typical workload power, peak/transient limits, and the system-level rack design rating.
