Of course, because NVIDIA can never be at fault, right?
They tested in Horizon Zero Dawn and Watch Dogs Legions, latter being NVIDIA sponsored title.
Yes, you said you didn't watch the video yet, but still you had to go and blame it being biased test just in case.
edit: just for the sake of it, it's showing even more dramatic difference in Watch Dogs Legions, where even 5600XT beats RTX 3070 on Ryzen 5 1600X, 2600X and Core i3-10100 at 1080p medium settings (1080p ultra 5600XT becomes the bottleneck regardless of CPU)
Not when you're examining CPU load between cards and they used cards from other performance points too.
