How many 400Mbps videos are there nowadays?

Maybe none today, but maybe later. I don't want to have to change all my computer again two year after the upgrade.

I have a NUC7i5BNK that I use for development. It is what I do all my VAAPI testing on. It's a great machine although NUC's are expensive.

Thanks for the answer! I'm not looking for a NUC, but I will look at the hardware.

Ok so just to be sure, I can get the cheaper CPU of Kaby Lake family, I won't see any difference than an i3? Even for a 400mbps video?

"Best Intel CPU for 4k HEVC 10bits videos?"

Intel Kaby/Apollo Lake and upwards.

Yeah... but which one?

Who is better than the other and why? Or maybe there is absolutely no difference between them for video playing?

Hi here!

I currently have a HTPC with Core i3 2120T on board. This one did a great work for years but is literally dying with a 4k HEVC 10bits video.

Time to upgrade. I tried with the Nvidia GT 1030 to keep the same motherboard, but this was not working at all. And next, I saw that the card does not support 10bits video.

Card returned. If only I saw your post earlier Klojum...

Well, I know have to buy a new Intel CPU and the corresponding motherboard.

I read that Kaby Lake CPU familly does support 4k HEVC 10bits videos quite well, but I would like to know which one is the best bet.

Here is my basic requirements:

Intel CPU trend. Did I already say it?
Compatible with the last stable version of LibreELEC (You don't say?!).
Be from the last Kaby Lake familly.
Can display at least 4K WHXGA (5 120 × 3 200) resolution over HDMI and DVI. I currently have a 1080p TV monitor which does not support HDMI signal correctly (I have to set audio force-dvi trough xrandr to have a clean image). But I want to be hardware ready for the next TV.
Low power consumption (T series). I only have a 150W power supply and I can't change it.
Can read fluently at least the jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv video. According to the website, this is the minimum to read UHD 4k videos.
Can read fluently yuv420p10le pixel format. This is the most used format of all my 4K videos. I will give you some NFO extract below.

Here is my bonus requirements (if the price worth it) :

Can read fluently higher videos than jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv. According to the website, jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv is the higher.
Is ready for future resolution like 8K, even for screen resolution than video transcoding.

Here is some NFO extract of video I want to play:

What are your advises about this? I'm used to i3 but I'm saw some CPU like Intel Pentium G4600 can do the work. Is that enough? Even for bonuses?

If you have some test videos you saw are you made, you are also welcomed to share!

BTW, if you have some mini-ITX motherboard supporting Kaby Lake processors to recommend, I'm hearing.

Many thanks for reading.
