Coming from the 1600af (2600) it is a big improvement. Techspot have it at 4%my brother as a 3070 aorus master and noticed a good uplift in average FPS and a big uplift in 1% lows.
he like me upgraded from a 5600 to a 5800x3d (i have the 5700x3d) there is literally 2% differance in the 2 cpu's
I upgrade so infrequently, the next GPU I get will probably be faster than a 4080S. I am using some odd resolution between 1440 and 1080.No but think about it another way, the 5700X3D probably wouldn't really bottleneck a 4080S so you'd get more mileage out of the older sys.
