NVIDIA RTX 40 Series Could Reach 800 Watts on Desktop, 175 Watt for Mobile/Laptop

Rumors of NVIDIA's upcoming Ada Lovelace graphics cards keep appearing. With every new update, it seems like the total power consumption is getting bigger, and today we are getting information about different SKUs, including mobile and desktop variants. According to a well-known leaker, kopite7kimi, we have information about the power limits of the upcoming GPUs. The new RTX 40 series GPUs will feature a few initial SKUs: AD102, AD103, AD104, and AD106. Every SKU, except the top AD102, will be available as well. The first in line, AD102, is the most power-hungry SKU with a maximum power limit rating of 800 Watts. This will require multiple power connectors and a very beefy cooling solution to keep it running.

Going down the stack, we have an AD103 SKU limited to 450 Watts on desktop and 175 Watts on mobile. The AD104 chip is limited to 400 Watts on desktop, while the mobile version is still 175 Watts. Additionally, the AD106 SKU is limited to 260 Watts on desktop and 140 Watts on mobile.
Making a difference between a power limit and a TGP is essential. While the Total Graphics Power is what NVIDIA rates its GPUs to run at, the power limit represents the amount of power that can be applied by board partners and overclocking attempts. It is not necessarily translated into TGP, meaning the final TGP values should be significantly lower.

ratirtyou say that you lowered the 3080 TI's capabilities by lower voltage and frequency (I assume that is what you meant by downgrading) and somehow you have more FPS? That totally makes no sense.
It does, cuz its power limited by default and frequency could drop below good undervolting setup, where is in optimal performance envelope. I would say its common with power hungry gpus.

Lowering voltage to find a sweet spot to gain frequency in a given power envelope sure can boost the card due to lower power consumption and lower DTP which give you some headroom. I doubt the card can be boosted when your frequency is manually lowered by a user from a default or factory settings and get more FPS.

I didn't say that.... you are fabricating your thoughts to be mine. I see that you have problem with understanding the written text. I will write it differently: undervolted 3080 ti with 0.8v and 1850Mhz its more powerful than default 3080 ti with automatic boosting to 1950Mhz which is constraint to 1680Mhz by boosting algorithm because of exceeding the maximum power target in the same game.

That is what the other dude said. Never said you were the one stating it.

Maybe I caught you in the middle :D and you were set up for that discussion, but this totally makes sense:

That was mine point.

Well lowering voltage and frequency at the same time will not bring you more performance. Will bring you less heat and lower power usage.

Good thing I bought a 1600w psu for my work cum gaming pc a few years back. My RX5800 gpu will be ready for an upgrade in time for the upcoming RTX4070.
