It does still depend on the games you want to play but with the most recent Beta drivers the performance is finally fixed in CyberPunk 2077 (along with work no doubt from CD Project Red).
Overall performance in the latest titles isn't that far off my Legions 3080M (clocking in at desktop 3070 Tier performance - but with 16GB of VRAM so none of its desktop counterparts problems...).
For example, at the same settings in Hogwarts - 3440x1440, high with a couple settings in medium and DLSS Quality / XeSS Quality (games reports same render resolution) the Legion is in the 80-90 FPS range whilst the A770 is in the 70-80 range. It is still behind in something like Destiny but half of the blame there can be with Bungie as based on my own experience, if you aren't running Nvidia then GTFO (seriously it took months for RNDA2 to be remotely playable).
So overall, both my A750 and A770 have come on leaps and bounds compared to the original launch drivers. There is still some sort of driver overhead causing performance to not quite be where it should be but based on the uplifts seen so far it will hopefully only be a matter of time before we see even more uplifts in the future. At the very least it bodes well for Battlemage (as long as the price is right of course).
