No iGPU on my CPU (5800x3d). So was straight software decode (well maybe AVX2?) against GPU decode. GPU route was 80W more.

joebonrichie's comment was excellent though - there is a new nvidia tweak that eliminates the GPU going to a high power state the second it sniffs video. So now GPU & CPU get me the same draw.

Yeah been considering using my mac air for when not gaming / messing with LLMs, but frankly struggling with it on UX.
