So what you are saying is that one can hope (not 100% safe) that Navi driven dGPUs will always have at least DP 1.4 HDR and HDMI 2.0, so perfectly for 4k (midrange games) and 8k (work and low end of games). And this is exactly what I need (in the near future).
What I don't get is why this is not doable with an APU - i.e. CPU+APU with about 65 W TDP capable of 8k for work and 2k and sometimes 4k to play with.
That's exactly what Haswell provided with 35 W to reach 4k (and games in FullHD or little less) - with no screens available when Haswell was released.
From your formulation I should lower my hope to see an AMD APU with 8k max res within Navi family (or at least 5k).
I am curious - is AMD capable of testing 8k res right now - i.e. are there 1st prototype displays to be connected with 8k@60Hz via DP 1.4 HDR?
Even if this has nothing to do with future products of any company but with testing possibilities you may not be able to answer this.
I would be quite interested in knowing how Intel managed to support 4k without the HW available at the time they had 1st chips and how currently companies support 8k. 8k prototypes had been there when 4k came up for < 500$ - but not with the needed DP/HDMI standards.
It is funny that Intel "supports 8k" only with less than 20 W for ultra thin laptops (Icelake; while their 95+W monsters are stuck below 5k using DP1.2 and HDMI 1.4 like old Haswell) which can not even reach 35 W Haswell performance (i.e. bad at FullHD with
mid range games) and AMD seems not willing (due to small demand ... so maybe understandable) to support below 70 W capable of supporting 8k.
But with Navi 14 capable above 4k (5k and 8k) there is one last question still open:
Is the support for DSC 1.2 currently in place for Navi 14 so that 5k+ is supported with the next gen of distributions like *ubuntu 20.04 LTS with the free Linux graphics stack or at least with the AMD driver for Linux?
This should be possible to be answered by AMD - right?
