Magnus peak rating was on 2014.

But he lost motivation afterwards, so that was not necessarily his peak, maybe he just yoloed a little after that. In his own words he's way past his peak. In recent interview he said his bullet no increment (most taxing on reflex/fast calculation) peak was around 7 years ago. I would assume his prime physical form came after his rating peak, because classical chess rewards deep study and consistency, and he admits all motivation was gone once there were basically no challengers and he distanced himself too much of the pack after Caruana also peaked hard.

But regardless, safe to assume his peak was 10-7 years ago. Still good enough to surpass current gen easily.
