How would you detect that GPUs are thermally throttling, and what is the right response when they are?

Correlate clock-event reasons, temperature, configured limits and workload timing. Use the scope of the slowdown to choose the next investigation, and distinguish intentional power limits from unexpected thermal constraints.

FEDITOR'S NOTE

Do not treat boost clock as guaranteed throughput or a spatial pattern as a unique root cause. Quantify a clearly scoped clock model and verify mitigation against actual useful progress.
