What Hacker News says
2 sourceslibvpx, the VP9 encoder library used in this test, has no support for any hardware encoder blocks for VP9 [1], so it does everything in software. There are ways [2] to compile some support into ffmpeg-with-libvpx that makes it able to invoke the hardware encoder in newer Intel CPUs (Skylake or newer) [3][4] (using vp9_vaapi) but it's doubtful that this was used, since their command-line switches indicate nothing of the sort.
x264 is a software-only encoder that provides no hooks into hardware acceleration. Their ffmpeg command line indicates that no hardware acceleration hooks of ffmpeg were used.
