This is my CPU-Z for anyone wondering. I'm getting 20 FPS encoding 1080p preset 8 AV1 video with just 2 fucking outdated Cortex A76 CPU cores running at 2.4 GHz.

This might actually be a really good/reliable way to benchmark phones desu. They can do their bullshit cheating for the first 30 seconds but the rest of the encode will force it to throttle down to true sustained performance levels.
