NVidia can completely shut down the RT cores, which AMD can't do yet. As such outside of RT the 5070Ti consumes quite a bit less. However if heavy RT is involved it doesn't consume much less than the 9070XT anymore. Also, keep in mind how the 9070 non-XT is consuming less power than the 5070 despite being more powerful and having more VRAM, which is mostly due to a lower clock speed compared to the XT model. AMD could for a hypothetical 9080XT simply reduce the clock speeds somewhat (like 2.7-2.8Ghz instead of 3Ghz) to stay within the 450W power budget. Or reduce the voltage a bit, which really does wonders on RDNA4 cards. |
While it's true that heavy RT makes the 5070 Ti's power consumption go up close to 9070 XT levels, the performance difference in heavy RT scenarios between the two GPUs is quite massive.

And yea, they could try and power limit it and do a few tricks but honestly, I don't think they will hold back if a 9080 XT were to be a thing since at that gpu class, power efficiency becomes less of a notable feature. Personally I think if they were to match a 4090 in Raster at 450 Watts, they will likely need 500+ watts of power. But if they price it correctly, the power consumption won't really matter to buyers.
And don't forget, you can also power limit Nvidia and get pretty good results.
