A dedicated GPU even if it's the MX130 would get the slightly better gamer. But a gamer would be quite upset at having to run games on low settings (most games today) but it will run The Sims 3 and 4 very nicely.
The Ryzen with it's on CPU graphics has been a nightmare for many users as they encounter random failures during gaming. I'm going with "it's not ready."
You didn't reveal what games you want to play so I'll write this is fine for non-competive offline gaming on low settings.
As to your statement about CPU GPU bottleneck, with such a low end graphics (either model really) the bottleneck is the graphics area, not the CPU.
an Asus Laptop A507UF
Processor: i3 -7020U
the MX130 faster in terms or core speed (correct me if im wrong) but the i3 is such bottleneck and it looks unbalance in term of both MX130+i3, and the Price also more expensive, while Ryzen 3 and Vega 3 are quite compatible since both of their performance are balance (correct me if im wrong)
i still can't sure. please help, thanks
