According to their own slides RT only is about 20%, rasta is the only one we don't have so I'm basing it on the worst figure from Nvidias own slides.
Yeh I'm waiting on reviews I'm basing it on the worst bar (RT) only, I'd like at least a 20% increase which should be possible given general hardware improvements, I'm not expecting 30% or above though. (I am prepared for worst case, but with me having a 1080ti the improvement regardless will be huge for me)
Either way I'll likely get the 5080 its at the price is want it, will be happy with a founders or AIB entry model at that price as long as it's under 1000.
Not sure if ill get a new PSU though I have a 850 but not with the right connection so I'd need an adapter.
