Full NVIDIA RTX 40 “AD104” GPU with 7680 cores and 400W TDP to match RTX 3090 Ti in performance

As usual, I'd take the power figures with a grain of salt more so than the rest as they could be testing out a custom AIB board. I do think the 70 series will be heavily held back due to the memory bus as as far as resolution is concerned. While it does have a lot more L2 cache compared to Ampere, it's still low so it will be targeting that 1440p where as a 3080Ti/3090 class GPUs will do better at 4k.

So, just to be clear about this hypothetical card that won't launch until 12-18 months after the launch of the regular 4000 cards: should we compare this 400W limit to the 3090 Ti's 890W limit or to the actual 450-470W that the retail cards use?

Because, if it's the former, well, it's kind of useless as no 3090 Ti can reach that power limit, making the comparation a bit flawed; but if it's the later... I don't know, I don't think that the 4070 Ti looks that impressive given that will use a new and improved architecture, much, much more efficient 5nm TSMC process and feature half the VRAM for only what, around 60W less?

If this hypothetical 4070Ti is really a 400W card, then Lovelace would be a pretty weak increase in terms of performance per watt.

I really hope this is the peak power consumption and regular use is quite a bit lower, otherwise I fear NVidia will get trounced by AMD in that domain (while probably retaining the pure performance crown).

Also, this wouldn't bode very well for mobile GPUs, as this would mean that the biggest GPU chip in laptops would only be something like a 4060 as the others would be too damn power-hungry.
