IIRC, you can also specify the GPU in your .drirc file.

cool, thanks, will try. Guess the biggest imperfection right now with PRIME is that the user needs to more manually switch it than it probably is quite dynamic and transparent on Windows (not really using Windows now, only guessing), with the MUX based setup is certainly is fully transparent on macOS, ... But as I said in any case working AMD solution is >>> NVidia binary stuff ;-)
By using this env var, the user can use per application settings.
For example, on fedora there's 'Launch using Dedicated Graphics Card' right click option. If I inspect process env vars, I can see that what does is actually exporting
Code:DISPLAY=:0 DRI_PRIME=1
The aforementioned is for OpenGL.
For Vulkan, one would have to export a different icd file:
Code:[mike@mikes-nest ~]$ VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/intel_icd.x86_64.json vulkaninfo | grep -i 'gpu id' GPU id : 0 (Intel(R) HD Graphics 5500 (Broadwell GT2)) [mike@mikes-nest ~]$ VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json vulkaninfo | grep -i 'gpu id' GPU id : 0 (AMD RADV CAPE VERDE (LLVM 8.0.0))

Hi Rene, I watch your reviews constantly. Thanks for your work!
You no longer need xrandr setprovideroffloadsink. A simple DRI_PRIME=1 env variable, would suffice.
Something like:
Code:[mike@mikes-nest ~]$ glxinfo | grep -i 'opengl renderer' OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2) [mike@mikes-nest ~]$ DRI_PRIME=1 glxinfo | grep -i 'opengl renderer' OpenGL renderer string: AMD Radeon (TM) R9 M375 (VERDE, DRM 3.27.0, 4.19.9-300.fc29.x86_64, LLVM 8.0.0)

I was surprised that no one had thought of mentioning the newer, unreleased i5/i7-88xxG CPUs.

I do not see mismanagement on the side of AMD. Polaris and Vega GPUs have the best performance/price ratio and are clearly the way to go for Linux gamers currently. The architecture is successfully integrated in consoles and also AMD and Intel CPUs.
An example for real mismanagement is, in my opinion Nvidias problem with all these GTX 1060-GPUs that remain in stock and the whole RTX-Series including the Raytracing marketing. It was clear that their decisions would put customers off on the long term. I'm sure they already regret to having built too big and expensive GPUs with useless features - at least regarding the current technical state.
Intel have also made many mistakes which causes mid term issues for them, but seem to have stabilized with the right decisions for the long term.
We will surely see many more CPUs with a strong IGP in the future and hopefully a memory architecture that suits the new demands much better. I see AMD and Intel as strong competitors on this market in the future but I don't see Nvidia.
Nvidia rules in market, because 99% of (powerful) GPU users are gamers. And, Nvidia focuses on gaming, therefore even without those fancy features not useful for games, nvidia dominates.
