Ryzen CPUs do not have IGPUs. If your low end gpu is PCIE 2.0 or 3.0, it will work just fine.
AMD will be releasing APUs eventually, so they will have CPUs with iGPUs...
then what is APU ? is it motherboard graphics ?
Accelerated Processing Units are CPUs+GPU combos from AMD. Usually 45-55% (give or take) of the die is taken up by the GPU. But, the beauty of the APU, is that unlike Intel's regular CPUs with IGPUs, AMD's IGPUs can do some CPU intensive stuff, typically never done on a GPU, making it a very fast processor in certain applications.
The only (HUGE) downside, is that there are hardly any apps or devs that are programming for APUs.
