Oh it's massively faster. I dunno 30% or so up to 40% or so faster at the higher resolutions. Both cards are nitro+ versions. It's also 33% or so faster at mining If thats your thing. Mind you if thats your thing just buy a 3070.
Unfortunately I live in a flat currently and both my PCs are running single cards each :O. Maybe when we move out in a couple of years I will look at a full rig if mining is still a thing.
