Tested RX7900XTX with ROCm7 power profiles
A user on Reddit's r/LocalLLaMA subreddit tested power profiles for the AMD RX7900XTX GPU using ROCm 7. The user found that a "quiet mode" significantly reduced power consumption by approximately 99W, resulting in a drop of about 9.4% in generation speed and 17.1% in long-context prefill speed. This power reduction also led to a decrease of around 11C in average junction temperature. AI
