AA hammers the bottleneck area of amd at the moment, so no aa alleviates it disproportionately to nvidia.
However dirt 4 has global illumination which amd handles FAR better then nvidia, as I beleive its the float that defines how well it will handle it, and in that regard, it can be handled with half precision, something nvidia shits the bed in.
when amd gets drivers and farcry 5 comes out, likely the first game utilizing half precision, we will likely see something interesting.
