While the GPU is enough for Dolphin, it's a last-gen part combined with a current-gen CPU which is an odd combination considering that even a current-gen GPU would actually be somewhat older than that CPU.
To put it into perspective, that GPU is on-par with the integrated graphics on a Ryzen 2500u (at least when paired with dual-channel RAM).
If you're going with an Intel CPU then I really would at least try to get an MX150 as your discrete GPU, otherwise for anything lower-end it could make more sense to instead go with Ryzen (though only with dual-channel RAM).
