I've tried some samples at FHD on a Intel Atom Z35xx SoC @ 1.33Ghz (4 cores x64 and a Intel GPU) with the latest Kodi (stable release, not Leia) (OS Win10 and 2 GiB DDR3 RAM) and it does not go well... (my living room HTPC... its a Intel Compute Stick)
Is it possible the Cortex A53 has more "power"/performance than a x64 core? Or what am i missing here? If that is the case i'm ditching the compute Stick....

Intel Atom is not able to software-decode HEVC, and it seems that hardware-decode is not used

No, A53 does not have more power, but there are ffmpeg patches using cpu and gpu for decoding HEVC frames. And most of that stuff is coded in inline assembler. So, we can say, in the meantime it is extremely optmized for Raspberry Pi

Kodi Krypton patches are able to decode 1080p 2:35:1 AR videos, sometimes with glitches, and Kodi Leia patches are able to decode FHD (no black bars) HEVC's without decoding errors

Quote:Also what is the average bit rate of those HEVC files you play?

Bit rate is not relevant for me, quality is much more important. Just tested HEVC video again, ffprobe reports
