I understand your concern and TBH have never understood this desire to always severely overvolt ALL cards out of the factory.
Can't they at least push a limited batch of cards that pass the quality control with some proper voltage settings?
Can you address your question directly to nvidia?
You and I know that voltage is the greatest enemy to any such chip.
Imagine if there was such an official 130-watt RTX 4070 (down from the ridiculous 200-watt official TDP) sold as single-slot, single-fan design, cool, quiet and small - win-win for the user and for the maker whose costs will be lower.
Instead, they do utter stupidity with those ridiculous oversized coolers, and then fixing the situation by offering normal coolers which suddenly are called "slim".
It's like everything is messed up at AMD, nvidia, MSI, ASRock, Asus, Gigabyte, etc. partners.
Nothing stops the manufactures from doing undervolting and "binning" I doubt Nvidia do anything to stop this because than Nvidia should stop the OC, Strix, AMP and so on models and Nvidia don't do that.
It's just anytime manufactures needs to do something more than use a near stock yet custom pcb with anything else than just normal stuff you need to buy more because they spend more time doing it.
If they some manufactures would release a 150-175W Edition this shouldn't really require much since all RTX 4070 gpu's can do this "
IF" I am not wrong they can still leave the single 8-pin of cause and do a bios switch which have the 150-175W mode enabled as default and than a stock mode and call it a day they with a lower than MSRP price tag it would be a hit.
Because seriously for me right now it's really tempting even I will be locked with Nvidia's stupid locks for DLSS, FrameGen and RT that I have never used but I can see the benefit from but at 130W for my electricity bill in late autumn/christmas my RX 7900 XT even with undervolting uses at least about 225-250W more if I am even that lucky it can go down to this which is still 100W more at 1440p but it's not like the framerate is 73 to 92% better than the RTX 4070.
I said before and I will again I would love to see AMD releasing a APU between 100-150W even 200W that can do the same as a dedicated card at 1440p medium/high at 100fps average but this might be too much since people and AMD/Nvidia I can also include Intel only thing about the next performance jump with a card using 500-600W that you are being told not to use because you need to save electricity I am tried of this.
This was the reason why I started this thread because at 130W I doubt you find something better, I haven't seen the more expensive 4070 Ti undervolted to 150W doing the same thing.
