Hi, what about PQ on last Android box like shield Vs Intel Box ?

If we are talking Kodi that can do auto Resolution Switching on either device to output video content at its native resolution to a 4K TV, then it somewhat depends on the quality of upscaling of all non 4K content your TV can do if you are chasing top PQ.

There are recent Premium 4K HDR TV’s that have there own forms of AI Super Resolution upscaling which will be superior to what any Intel device or comparatively cheap Android media player can do. See the following post for details:

AI Super Resolution Picture Upscaling on 4K TV's (click)

Is still Intel render better than Android for PQ ?

There are too many variables to answer that question properly.
Depends on what content you watch, modern HEVC (h.265) properly encoded video content can package a better effective bitrate and give you a higher PQ for the same file size vs using older h.264 encodings.

Depends also on what type of display you are connected too, if it supports HDR and how good it’s TV picture upscaling and picture processing is.

If you have crap upscaling on a 4K TV then the 2019 Shield’s even limited AI upscaling of non 4K content is better than nothing. It will be better than anything Software upscalers can do on Intel Hardware. (Read the “Here is the Secret Behind” link in AI Super Resolution thread)

Just be aware some users report the 2019 Shield's AI picture upscaling produces overly sharpened picture outputs. Others love it. So it's seems it's highly subjective and depends what people have to compare it to.

I'm thinking about the switch from Intel Box due to Prime video app (sd resolution on non Android box)

Be aware if you are thinking that you will get reliable AI upscaling of non 4K Prime Video content well you might run into problems:

2019 Shield AI upscaling Limitations and possible problems:

#1 2019 Shield AI upscaling is limited to video content output at 30fps/Hz or below. it will not work for Live TV or 480p content.....
#2 That means for 24p content you have to use auto Frame Rate Matching which is Beta status on the Shields and uses workarounds for Apps like Prime Video and Netflix.
3# The Amazon Prime App when using such auto Frame Rate workarounds has been reported to throw up HDCP errors - it thinking video output is being hacked and copied.

You might be better with a dirt cheap Amazon 4K Fire TV Stick if Amazon Prime App is all you want.
Really an sort of device with proper L1 DRM and HDCP 1.x/2.0 is going to give you better than SD res. Amazon Prime video output quality.

The best picture quality output of non 4K content these days is found by using Apps on Premium 4K Smart TV that do some form of AI Super Resolution upscaling and have powerful dedicated picture processors as well,
AND also feeding unprocessed non 4K video content to such TV at the content’s native resolution by using Kodi auto Resolution Switching.

^^^^ Both of those is what I now do with my 2019 GZ Panasonic OLED.

Sorry i'm not able to quote and reply (old gen man )

thank you for you reply, i try to reply even if my english is terrible

1 and 2 )I'm not talking about upscaling or autoresolution (solved with android 8 ? ) also cause my tv is a plasma 2k (so no 4k e no hdr , until i don't change tv   )

i'm talking about PQ thanks to render method like Vaapi and Egl > https://forum.kodi.tv/showthread.php?tid=231955 VS android render method 

See here for example about Android PQ:

And if i rembember correctly nvidia shield box was the only one with correct rgb space colour, it's ok for all android box (autoresolution, rgb , pulldown ? ) or if i want the best pq from android box shield box is the only choice ?

I asked about PQ cause i rembember that some years ago Intel PQ was better than Android


3) i read your post about Amazon nad shield problem and i found out that your suggestion to buy a fire stick is the best choice

thank you
