I saw "Adobe Premiere Pro" benchmark everywhere for cross-platform. But I wonder if their output video quality is the same (when GPU/hardware encode enabled, they using diff codec)? And in the above benchmark, is it comparing GPU accelerated M1 Max to non-GPU enabled PC (even they have a RTX)? Look at the chart, 3070 is slower than 3060. It's non-sense. I watched a youtube video before, their M1 Max is twice faster than RTX 3090 machine on their Premiere test. What makes the diff :s
