SVT-AV1 has massively improved encoding speed. I was getting ~4x encode speed with some heavy compression (barely any noticeable quality drop) on 1080p/24fps footage on my Ryzen 7 3700X just yesterday.

4x means that you can encode with 1/4 the time of the video, right? That sounds nice, a lot more practical than when I tried before.

To get a rough idea - is it faster or slower than HEVC encoding on a CPU (without any hardware encoder)?

It's good and getting gooder.

Just give it a try using https://github.com/Alkl58/NotEnoughAV1Encodes or whatever, svt-6 is fairly quick.

For cpu I don't know but h265 hardware acceleration ASICs are mainstream contrary to AV1. Also h265 can reach higher compression level than AV1 although the difference is relatively small apparently. However technologically AV1 is largely obscolete since h266 stable has been released.

Every study I've seen shows AV1 beats H.265 on VMAF at all bitrates. H.265 never got significant browser support, and I don't expect H.266 to either. https://caniuse.com/hevc

I have seen a scientific paper a few weeks ago stating h265 was ~7% smaller than av1 on tested dataset. Although maybe it's dataset sensitive or differ because of the metric? (maybe it was PSNR or SSIM?) Anyway any data on AV1 hardware decoding energy consumption vs h265? That is probably the main differentiating metric of interest here
