[SOLVED IN COMMENTS] Vega 8 vs r 535?

Question

Iron

Hello again! Then I decided to fork out for a laptop and take a bunch of AMD Ryzen 5 3500u + AMD radeon 535, but just before pressing the "buy" button, I came across a video comparing the built-in vega 8 processor with r535. And in most cases, vega pulled ahead. As a result of surfing, I found information that with direx 12, in some cases, you can use two cards at the same time.
Nevertheless, I did not find an unequivocal answer whether SUCH a discreet is needed. + On Vega, you can try to remove the limit on the memory that it takes from the system ...
In general, help with the decision, thanks in advance
