Keep a 4080s or take a 5070ti?

[AndreX86]

I would say to get it if you can at MSRP. It's worth it for MFG IMO and you can likely sell your 4080s for the same price or more.

If the difference is so little you would hardly notice or tell then I don't think it really matters. Power Efficiency simply doesn't really matter for this comparison in my opinion. Just because the 7900XTX is a smidge bit faster than the 4080S (usually only by 1% to 4%), suddenly didnt mean people were recommending the 7900XTX over the 4080S in raster. I think the same logic applies here.

Not to mention, OP mentioned overclocking a potential 5070Ti to beat a 4080 (which it already matches as is) which opens up another can of worms for power efficiency, and ATP if your gonna overclock power efficiency probably isnt your concern anymore. And even in this regard, an overclocked 5070Ti from what im reading is still well within 5% difference range. Cooler matters too in that regard but it seems pretty consistent across all the charts I saw for different models (avoiding FE for comparison due to no FE card for 5070Ti)

TL;DR, power efficiency, and by extension, other stuff such as raster, really dont matter in this arguement. I dont see a point in bringing them up. Your choice is gonna entirely hinge on the features. (and price, if you can get a good price of course.)

5070Ti if its at a price similar to a 4080S (which the cheapest ive seen are), if you already own a 4080S, you should pass unless you value the features exclusive to the 5070Ti and can actually get it. If you don't, and were considering getting a 4080S, then, in that specific instance, go ahead. Even more so if you can buy a 5070Ti at its actual MSRP. If your not an american thats a factor too, due to stuff like VAT, but thats getting into a whole other can of worms.

You're still missing the point.

7900XTX vs 4080 had pros/cons. 7900XTX ~5% faster in raster, bit more VRAM (debatable if a real positive beyond bigger number better, since no CUDA for professional applications and games don't use 24 GB), slightly better in Linux (at the time), 40% slower in RT, no DLSS, more power draw etc.

5070 Ti vs 4080, 5070 Ti wins or draws in every category. OK, it's only 5% more efficient than the previous most efficient card available. But again, doesn't matter if the win is small, there's no downside to going with the 5070 Ti for the same or less money.

OP is clearly OK with the hassle aspect, he's asking which is the better card, and the answer is obvious.

I would say to get it if you can at MSRP. It's worth it for MFG IMO and you can likely sell your 4080s for the same price or more.

He doesn't need to sell it, it's within return window.

If the price is about the same, then easily the 5070ti, new tech with new features and it will be faster with newer drivers.

Have 4080S? Keep, unless;
Value DLSS4 and MFG? Get 5070Ti.

Return window open? If you have a guaranteed way of getting a 5070Ti, get 5070Ti. But do NOT pay more than 4080S MSRP. Ideally, pay less.
Don't have one but wanted it, now 5070Ti out? Get 5070Ti.

This is basically what I would recommend OP. 50 Series launch has been rough, just don't be a idiot when buying a 5070Ti and you should be okay if your doing that. OC, Power Effiency, Raster, etc are not what you should worry about. Just focus on the features, or other small things the 5070Ti has over the 4080 if it benefits you. Or if you already can get one for same / smaller price.

You are exactly highlighting more of what I'm talking about. Nobody bought a 7900XTX because its faster in raster. They bought it for other reasons. This comparison is no different, except its actually a very close comparison. So why should power efficiency even matter? Just because the 7900XTX on paper wins in raster doesn't mean it actually matters.. you can still value that small, microscopic win, that nobody will really realistically care about or even notice, but the comparison is so close here it doesnt matter.

I think we both are saying the same thing but just applying it in different ways. And for me, a microscopic win might as well be a draw.

well dlss4 is also on 4000 cards, what are the other features? mfg? i don't know if i ever will use, i have a 120hz oled tv for game
and a feature i will miss is physix

If you're still within your return window and are *certain* you can get a 5070Ti for less money than the 4080S cost you, I guess you can consider switching them.

Advantages of the 5070Ti:
- barely more efficient
- more headroom for overclocking or undervolting due to 5nm process increment
- more memory bandwidth (if you're looking to run local LLMs and don't have the budget for 24GB+ VRAM)
- MFG, if you care about that
- supports newer features that may or may not become relevant in the future (neural rendering and textures)

Advantages of the 4080S:
- more mature drivers, proven hardware design
- very minor performance advantage on average and slightly less minor performance advantage in raytracing heavy workloads (in spite of the older gen RT units)
- lower chance of a 'dud' that has more units deactivated than it should
- you already have it in hand
- faster in compute heavy workloads such Stable Diffusion

Value DLSS4 and MFG? Get 5070Ti.

DLSS4 works just fine on a 4080S

"condoning such actions"

My dude it's 32 bit software for which a direct replacement has existed for more than 15 years, and this is 2025. Should hardware manufacturers keep supporting all standards for infinity? Seems like a waste of die space.

Besides, it's not like the game is unplayable without PhysX, or that it will magically make a 15 year old game look contemporary.

Seems like a very similar issue to how modern fast computers have problems running very old games, as framerate tied to physics etc and the sheer speed of modern hardware causes stuff to break. If turning on Physx on a game from the 2000s is critical, I'm sure there's millions of old GPUs/systems on Ebay or in your garage gathering dust.

Could NVIDIA write a translation layer similar to what Intel did for old DX games with their discrete GPU release? Maybe. Is it worth it? Unlikely.

My bet is this whole "issue" was the first time most people even remembered PhysX existed.

I'm guessing NVIDIA made this move to 64 bit only CUDA/PhysX for the same reason Apple went 64 bit only, Intel tried to, and Android is in the process of doing, it simplifies things and allows more focus on currently important things.

Correction, the newest ARM processors for Android already only support 64 bit code.

Started with the Pixel 7. I didn't hear much outcry then.

But hey, NVIDIA bad right?

If I ever dared mentioned that I prefer nvidia over amd cards for the physX support at any point in the last 5 years in these forums, people would nail me on the cross. and would suggest that im just trying to find excuses not to buy amd. Now that nvidia removes support for it, it became a news worthy issue.

DLSS4 works just fine on a 4080S

well dlss4 is also on 4000 cards

To be fair ive heard back and forths on that, could be because MFG is often labeled as part of DLSS4 when it really isnt so.. yea. My fault there. In that case, even less reason to trade out a 4080S unless you like MFG.

 

[Vayra86]

It pretty much is, same perf, more features, better power efficiency. If he can get it cheaper too and return the 4080 what exactly is your problem?

Yes, and the featureset is slightly changed, you might miss some ROPs, and the driver branch is exhibiting major problems.

Its completely pointless to sidestep to a 5070ti at this point. Same perf - that really already sealed the deal. Early adopting hardware is never great, and this gen is exceptionally not great at that.

You're comparing PC gaming to an Android phone. You don't get it at all.

Its the same reason Windows still has backwards compatibility.
