I want to update to a Ryzen APU, desktop or laptop.
With Ryzen 4000u series coming soon, how is the performance and experience with iGPUs?
Does it support opencl for rendering?
Also, I would be on Linux.
Sure, but it has such few shader units you will likely find the cpu cores to be faster. Might still be worth trying out the cpu+gpu though.
For the new viewport though it ought to be fast enough to work with though, which is probably the most important variable here.
