What is the suitable H/W compatibility for av-1 encoding

Some videos are transcoded, h264 on ARM machine, h265 on Intel Skylake and av-1 on Intel RocketLake. File savings are better with av1 at the same quality but still at a high computational cost.

Avg computational cost in secs,

h264 => 14.77
h265 => 25.66
av1  => 85.00

No luck on wikipedia, what is the suitable H/W compatibility to encode in av1.

av1 encoder used, libaom-av1.
