NVIDIA GeForce RTX 40 Series Graphics Cards Could Consume Up to 850 Watts of Power, It’s Claimed

The rumor mill has begun turning again with new purported insight regarding NVIDIA’s next-generation graphics cards, the GeForce RTX 40 Series, and this time, they indicate that the new family based on green team’s new Lovelace architecture could feature models that consume a higher amount of power than anyone might’ve imagined.

According to a tweet shared by leaker Greymon55 today, NVIDIA GeForce RTX 40 Series graphics cards that leverage the flagship AD102 GPU currently feature TGP ranges of 450 watts, 650 watts, and 850 watts, substantial increases over the GeForce RTX 3090’s 350-watt TGP. Greymon55 clarified that these specifications aren’t final, but higher power consumption in next-generation GPUs seems like somewhat of a sure thing based on other incoming advancements such as PCIe Gen 5 power supplies, which can deliver up to 600 watts of power through a single, new 12VHPWR connector.

Another prominent leaker, kopite7kimi, chimed in with some thoughts regarding the GeForce RTX 40 Series’ alleged power consumption as well, but they suggested that the figures should be taken with a grain salt. That said, they have heard similar rumors that suggest NVIDIA’s next flagship could consume up to 800 watts of power.

NVIDIA will release its first GeForce RTX 40 Series graphics cards in September, suggests Greymon55.

I am not clear at the moment whether one model has three TGP ranges or whether it has three models but the TGP number of the AD102 is 450W-650W-850W, of course this is not the final specification and there may be some deviation.

That’s just a rumor.
I’ve heard 450/600/800W for 80/80Ti/90 before.
But everything is not confirmed.

Some NVIDIA GeForce RTX 40 graphics cards with AD102 GPU are now rumored to consume more than 450 watts (VideoCardz)

• This new [Ada Lovelace] architecture has been rumored for a long time to increase power requirements to insane levels, even higher than RTX 3090 Ti now expected to be 450W GPU.
• The AD102 GPU is now expected to be using TSMC N5 process technology. This processor is supposedly using a monolithic design with an estimated die size of 600 mm².
• According to previous rumors, the AD102 might feature as many as 18432 CUDA cores, but of course, such configuration might not be immediately available for consumer GPUs, if they are being planned at all.
