AMD or Intel

[madboy74]

Hi,
I want to change my PC. I have two ideas: AMD AM4 Ryzen 5 2400G or Core i5 8400. I have a 4K monitor with 30bit color depth.
If possible I need 30bit support for my monitor. I will use it for the GIMP, Inkscape and Darktable under Ubuntu 18.04.
Which is the better for me?

Either AMD or Intel will work for your use case, but you will need fairly recent software. Ubuntu 18.04 is not going to be sufficient, unless you upgrade kernel/xorg/mesa through PPAs.

Ryzen 2400G (Raven Ridge) will work best with the upcoming kernel 4.17: https://www.phoronix.com/scan.php?pa...rovements-4.17
30 bit color support needs X.org server 1.20 if used with GLAMOR acceleration https://www.phoronix.com/scan.php?pa...lor-30-Support
also Mesa 18.0 is needed https://www.phoronix.com/scan.php?pa...s-10-bit-Color

About Intel, I think some chips do not support 10bpc over HDMI, only over DisplayPort. Double-check if that is your intended use case. I would however prefer AMD anyway due to the better GPU.
