A user on r/LocalLLaMA conducted tests on the MI50 GPU, focusing on its power consumption and performance under various power limits. The tests revealed that generation speed is highly resilient to power throttling, with 100W delivering nearly 97.5% of the speed achieved at 190W. Significantly, operating at 50W provided 70% of the peak generation speed while using only 26% of the peak power, resulting in a 3.6x improvement in energy efficiency. The analysis also indicated that prompt processing degrades faster than generation speed when power is limited, and for inference-heavy tasks, 50W appears to be the optimal operating point for the MI50.
