If you want to game without a GPU, you need a CPU with integrated graphics (that is a CPU with a graphics chip built into it)
Gaming on integrated graphics is a low end experience, but will suffice for low end games like LoL, CS:GO, etc.
If you want to go the route of AMD Ryzen then you need a CPU with the letter G at the end.
Alternatively, you can get a better (but still low end) experience with a budget entry level graphics card and a more budget oriented CPU like a Ryzen 3 CPU.
I can see if it's possible to get away with actually getting you a graphics card, but to do that I will need the following information.
Otherwise get the Ryzen CPU with a G at the end.
Country
Budget in your own currency
What products must be included (i.e. CPU, RAM, GPU, motherboard, PSU, etc.)
If you already have certain components, tell me them as well as their make and model.
