I agree, my 780m is quite capable in most games. Depending on the resolution & settings even cyberpunk 2077 is playable at 60fps. MS Flight sim though hits (presumably the memory bandwidth bottleneck) hard.
Sort of. The generation is RDNA2, but it's unlike all other RDNA2 chips because the focus is so much on energy efficiency (and the APU has its own codename, van gogh)
