How big is the jump in performance from 2070 S to 3070 ti?

[Nuclear_Fermion]

I was going to upgrade to a 3080 but they're right at the limit of what my PSU can supply (750W) so I Was thinking about going with a 3070 ti. Is the performance increase noticeable? I game at 1440p and I noticed my 2070S does struggle a little bit with RTX on.

Look at the percentage difference on here.

45% So a sizeable jump.

Get a 3080, the 3070ti isn't a good deal, and a good 750w PSU is okay

Comparison of raw specs doesn't really tell you how much real world difference there's going to be.

 

Search for the game(s) you play, search for the GPUs and try to find benchmarks or e.g. YouTube videos that include both

Depending on which 3070ti you get, it uses nearly the same power as the 3080. Like ten watts less...Pretty insignificant.

Hmm you're right, the price difference isn't too big either. Might stick to a 3080 then

Which 750 watt psu have you got, just out of interest?

What are your full system specs?

[JKRsega]

Corsair.  Meant to be a reliable unit.

So going off of Tom's Hardware, TechPowerUp and a couple other reviews on your CPU and 3080's. I am getting 320W for the GPU under load, and 180 Absolute MAX for the CPU (avx torture test with the CPU OC'd to 5ghz) so that is only 500W, that gives you 250W left over for the rest. I'd say you are in the clear.

Yep, but in fact the issue with 3000 card is not average load (cause here a 550W could do then !), it's the transient spikes that can double the GPU wattage for some microsecs (look at GN vid on this)!

Then what matters is that the PSU is sturdy enough to not trip on those spikes, not only the max load. OP having a good RMx750 (that should trip around 1000W) he shouldn't have any issue

rm750x should be plenty though, right?

Yes, the 750W PSU having issues with 3080 spikes are mostly SFF or crap, this one is neither

Took that into account. Transient spike (20ms) of the noctua 3080 only puts the gpu to a sliver over 400w. Still plenty of headroom with his kit.
