Question Buy 4080-S or 4070TI-S ?

[gaav87]

I want to swap gpu's i currently have 6800xt and 7800xt
But i want something with more performance but the catch is max power 220-230W.
Will the 4080s UV at 220-230W lose alot of performance vs stock or just go with 4070tisuper ?

If you are not going upgrade anytime soon again then 4080S and money is no issue.

But I would save $200 and go for the 4070ti super. It’s only 18% faster than the 4080S.

When power is a concern and cost is not, one can always go with the silicon that has more execution resources and downclock to maximize efficiency. Both GPUs use the same die, one has more SMs enabled. The one with more SMs is going to use less power at iso performance (assuming similar die quality). The only catch is the default configuration, but even the 4070TI-S would need custom settings to run @ 230W.

TDP:
4070Ti-S 285W
4080-S 320W

A 4080S will give you somewhere between 40-50% more performance at stock TDP. It's also the most power efficient GPU currently.

When you power limit a 4080S to 230W I would expect you would maybe get around 25-30% more performance vs your current cards. Which IMO isn't enough to justify the $999 price of entry when the 5080 and 5090 are expected at some point in the next 6-9 months.

For some objective numbers I ran the 3Dmark Steel Nomad benchmark on my MSI 4080 Super (Ventus OC model). It's on a 7800X3D CPU.

Stock TDP/settings:


72% Power Limit (320 x 0.72 = 230.4W):


At least in this particular (very short) benchmark it attains ~91.9% of the FPS at 72% of the power limit. Not bad. Not bad at all.
