Well according to notebookchecks comparison the rx 550 is about 30% better than the mx150 in benchmarks. So taking into account the minus 10-15% an adding a worst case scenario modifier the rx540 is about as good as an mx150. Even a bit better... which is pretty impressive to be honest. My only concern is now with the cpu that its paired with. An fx-9800p an that is not even in the same leauge as the i5-8250u paired with the mx150. But i think it may still worth the much lower price compared to the intel solution. Or am i missing something?
