It’s got less memory as far as I can remember, yes. The CPU and GPU are ever so slightly less powerful too, but not by much. And yes I believe it’s output is 1080p as opposed to 4K. There is of course a difference but I don’t overly notice it, not at the distance I sit from my tv. My tv is a 55’’ OLED, and even at 1080p it looks frankly amazing.
