Nvidia's new FAQ tells consumers everything they need to know about the GeForce RTX 40-series GPUs and power supplies.

Nvidia Clears the Air on GeForce RTX 40-series Power Requirements : Read more

The power requirements have stayed the same or reduced while delivering substantially more performance. RTX 4090 draws the same power as RTX 3090 Ti, the RTX 4080 16GB draws 30W less than RTX 3080 Ti, and the RTX 4080 12GB draws 65W less power than RTX 3080 12GB.

This is such an absolute horseshit statement, I can't believe they have the audacity to print it. Litterally comparing every single one of these cards to the next card up the lineup in the 3000 series.

"However, the 30-cycle specification is the same standard for any PCIe or ATX connectors that have been with us for years"

Oh really? 🤔🤔🤔

What are you talking about? The model names are completely irrelevant to the point Nvidia was making. Even without exact performance numbers for the 4000 series, it should be pretty safe to assume what they have said is accurate. More performance with less power used.

This card will need this much wattage... that card needs that much wattage... and quality is once again thrown to the wayside.
Then reviews show us what power transients are like for these - whether they are worse than Ampere or not.

No, it is relevant. The question on that FAQ asking about power requirement compared to last gen, and Nvidia says it stayed the same or reduced (1st point) while delivering more performance (2nd point).
There is no argument about the 2nd point, 1st point is 100% wrong and misleading.
Basically if you are now using 3090, you probably want to upgrade to 4090 and not to 4080. If you followed Nvidia PSU recommendation, your old PSU will be 750W, 100W less than Nvidia recommendation. Are you telling me that is accurate?

Let us move to the not so 4080 tier. Compared to 3080, this 4080 tier is a joke because they use smaller chip for the 16GB variant, and an even smaller chip for 12GB variant. In the 3000 series stack, 4080 12GB would be 3060. At the very least they should call it 4070, but no, they just want more money from it thus called it 4080 12GB. Because of this, comparing it fairly will be difficult. If you just drink Nvidia kool-aid, then yes, Nvidia is kinda right. Kinda because they didn't compare 4080 16GB to 3080 but using the Ti variant. But since they have 2 4080, then I guess it is okay by Nvidia's standard. But if we want a real comparison, 4080 16GB is using similar power to 3080 with the same PSU requirement, thus 3080 owner can upgrade to 4080 16GB without changing their PSU. 4080 12GB should be called at least 4070 and I'm being generous here, then it is 4080 12GB 285W vs 3070 220W GPU.
Chip size wise, the comparison should be 4080 16GB 320W to 3070 220W and 4080 12GB 285W to 3060 170W.

Personally I don't mind if the new card is using more power since it does pack more transistor per area, but Nvidia is definitely trying to make it look better than it is (from power requirement perspective, not performance).

nVidia screwed up 40xx cards by lying-by-omission about their 4070 being a 4080, insulting EVGA until they dipped, and now this mess. At this point they can talk all they want. If I were to buy one of their cards (I'm probably gonna go Intel or AMD this time though even though I've never tried their cards before), I'd get a new PSU as well. Maybe they're telling the truth but my trust is very low in their brand right now.

Or better said: It's not really distrust, it's trust (12GB).

It isn't. The 3000 series had so many variants bunched together that you can pick lower cards and Nvidia is still right. Don't like comparing the 12GB 3080Ti to a 16GB 4080? Fine, the regular 12GB 3080 12GB has a 350W TGP just like the Ti. No change, but bigger performance advantage for 4080. Don't like that one either? Even the original 10GB 3080 has a 320W TGP, which is equal to the 16GB 4080. Nvidia is still correct. Equal power, 60% more VRAM, better performance. Don't like the 12GB 3080 compared to the 12GB 4080? Looks perfectly logical to me. You can go down two tiers to the 8GB 3070Ti with a 290W TGP which is higher than the 285W for the 12GB 4080. Less power, twice as much VRAM, better performance. Dropping all the way down to the 8GB 3070 would be BS as it uses regular GDDR6 VRAM which uses significantly less power than the the GDDR6X in the 4080. 4090 vs 3090Ti? It was pretty widely reported when the 3090Ti was released, that it was basically a test platform for what the 4090 was going to be. Equal power, $400 cheaper, same amount of VRAM, should be much faster.
