@Star-Eagle AMD's APUs (not the Ryzen/Vega based ones coming later this year) will have awful performance in KSP. Older i7s are still good, a i5 2500k on desktop is still a good processor for gaming. Separate graphics will definitely be better as well, but a laptop with a dedicated GPU will be upwards of $600 in most cases. And AFAIK you can't upgrade laptop GPUs, unless you have a laptop with a Thunderbolt port, a new GPU, and the GPU docking station, which is about $500 for a RX 480 and all the other stuff, as well as it not working on older systems.
