    What is "300%" supposed to mean? CPU total usage also is questionable with hyperthreading enabled.
    Anyhow, it's the peak bitrate that's crucial, and that YouTube 4k 60fps VP9 8 bit video caused dropped frames for me with my previous 2500k OC in Firefox.
    Not to speak of mobile devices, noise, heat and limited background capatibilities due to expensive software decoding.

      Ah, yes? Did you even specify the used CPU?
      If it's the 6700k with HTT, it would likely mean physical cores barely have more than one quarter of computing power unutilized, which completely backs my point.

          I made a quick test with an 1080 H.246 video I have on hand. I'm running mpv on Gnome Wayland on a Skylake i7-6700HQ (45 W TDP) laptop. It uses 21 W in idle, 25 W, 10% CPU, with hardware decoding (iGPU), 31 W 70% CPU with software decoding.

          I also tried with a 10-bit 4K HEVC and it's unwatchable with both software and hardware decoding at 58 W (powersave governor) / 65 W (performance). I haven't tested on Windows.
