Kaby Lake supports 10-bit 4K HEVC hardware encoding, but in QuickTime using Quick Sync, only up to 8-bit is supported. This means for hardware HEVC encoding on the Mac, 6th gen Skylake and 7th gen Kaby Lake are identical.
I wonder if things might change in 2018 with macOS 10.14. Maybe they'll introduce 10-bit encoding? Or maybe not. If they do, that would only come to 7th gen Kaby Lake or later.
BTW, I've noticed that the Finder takes a little bit longer to open HEIC files than JPG files, even with Kaby Lake. JPGs open instantly whereas HEIC files have a small delay on my 2017 i5 iMac. Not a big deal, but a minor disappointment.

Pascal and Polaris graphics cards support HEVC decode/encode. In Windows and Boot Camp it’s great.
Apple has chosen not to include this in their AMD drivers in order to force computer upgrades at some point.
Nvidia hasn’t implemented it yet in their Mac drivers because they are perpetually in beta.

When the new Xeon Macs ship, it'd be interesting to see if Apple enables hardware encode/decode on the discrete GPU. AFAIK, xeons don't have Quick Sync.

But I'm not sure how third-party apps can use Quick Sync. In think functions are exposed in VideoToolBox.framework.

It could just be a quicktime player limitation. The only HEVC option offered is one checkbox. We'll see when Apple updates FCPX to use HEVC (an VR), as promised.

Ah, I see it was a h.264 video, I mistook with the other video link. But still 550ti supports maximum 2048x2048 h.264 video decoding. Larger will have to be done on the CPU.
IINA released HEVC support in today's release. I'll post my readings soon.
My 2017 MacBook Pro 13" runs the jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv (http://jell.yfish.us) file perfectly in both Quicktime and IINA. Very happy. I presume if it can play that then it's fine for anything.
Awesome!
That was quick. I am glad I didn't spend time repackaging mkv files for QuickTime.
Here it is, the numbers, in case anybody is interested. I posted about this here.

Same here. Downloaded the file to test it out.
My 2017 13" TB MBP can't play it in IINA 0.14.
This doesn't seem right. (Left - QT | Right - IINA)
1. IINA's image seems too vibrant compared to natural looking QT's.
2. In this particular 4K of Life of Pi, the sky looks unrealistic
(This is a 2GB 1080p for comparison) QT | IINA
54GB 4K Bluray Remux in IINA
3. There is color banding in 4K. Look at the sky. Unexpected, right?
54GB 4K Bluray Remux in IINA
All these started since IINA released update for HEVC support. I'm getting too many crashes while scrubbing (both Touch Bar and touchpad). Anybody else noticing any of this ?

The 1 GB version of that LG Cymatic Jazz file seems to work fine on my 2017 12" MacBook with IINA 0.0.14. However, it uses about 50% CPU.
http://4kmedia.org/lg-cymatic-jazz-hdr10-uhd-4k-demo/
Is that the version you tried? Note that I didn't check if it's always playing at 60 fps, but playback was smooth.
I googled the exact keyword given by the poster and it landed me on this page: http://4kmedia.org/lg-cymatic-jazz-hdr-hlg-uhd-4k-demo/
And it doesn't play.
Man, do you notice any weird behaviour in IINA's latest release. The post of mine above; if you happen to know solutions for any of those, pls share.
That one stutters for me too, with over 90% CPU usage.
But like I said, the other version of the same video works fine, despite having an even higher bitrate.
The other version is an mp4 file, the problematic one is a ts. But why should this interfere with hw decoding, I don't know.
And Quicktime won't open the mp4 version, btw.
I also find the colors in IINA to be over saturated, but the files don't work in quicktime so I can't compare.

I don't think I've ever used a standalone ts file until this week. I've just seen them on disc. Not sure why they're using the ts file format for this. Also, I am not sure if the problem if the file format or the HEVC encoding method, etc.
Anyways the mp4 HEVC file works fine.
Correct.
Interesting.
With the Jazz Cymatic with the 1.2 GB mp4 file, my 2017 i5 7600 sometimes stutters on it with IINA 0.0.14.1. However, it's only using 10% CPU.
With the Jazz Cymatic with the 0.77 GB ts file, my 2017 i5 7600 plays it better but also with some stutter in IINA 0.0.14.1. However, it's using up to about 80% CPU.
So it seems the ts file is being decoded in software, mostly with success, but not perfectly.OTOH, the MP4 file is being decoded in hardware, and it works, but with less smoothness.
Meanwhile, on my 2017 MacBook, the MP4 plays perfectly in hardware both in IINA 0.0.14 and in IINA 0.0.14.1, with about 25% CPU usage.
EDIT:
I rebooted the i5 7600 iMac and now the mp4 file works perfectly with hardware decoding.

I noticed something weird yesterday.
Life of Pi 2160p Remux I downloaded from rutracker had Russian as primary audio track. And the images were over saturated and there were color banding. I decided to check whether it's the file or the player. Wanted to remux it so I can see it in QuickTime.
I used Subler which although screws the 8ch audio by down mixing it to something useless, it created a 55GB mp4 container. Interestingly in QT it looks extremely washed out. The colours are dull. The CPU usage was as expected i.e. lower than IINA and there was no color banding as well; although there wasn't much of color to see the banding anyway.
I googled a little bit but didn't find any suitable answers. I spent couple of hours muxing but nothing positive happened.
