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

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

Terminal

Input #0, matroska,webm, from 'unfired-rush-x265.mkv':
Metadata:
encoder : libebml v1.3.4 + libmatroska v1.4.5
creation_time : 2017-04-26T15:59:54.000000Z

So no hope for some optimization on my Atom platform... that sucks :/ On the other hand its awesome that the Pi 3 is able to handle the codec using optimized code .

Wow the samples i have are in 16:9 AR and with 30 Mbit/s bit rate... and 1080p or FHD... maybe i can test with a lower bit rate and see what is the performance ?
And yes i also don't care about bitrate but i do care about quality, and sadly the best ones have much higher bit rate :/ (or again am i missing something ?)

2:35:1 AR with no black bars? So it stretch the image or what? If so is that optional (because i don't like stretching the image) ?
Thanks
