Nvidia may have an even more monstrous GPU coming up

A new rumor suggests that Nvidia may be working on an even more power-hungry RTX 40-series graphics card than the flagship RTX 4090.

The company has reportedly built a test board with a total graphics power (TGP) of 900 watts, topping every previous expectation as to the card’s power requirements.

In fact, there is another full-fat AD102 SKU with 900W TGP, 48G 24Gbps GDDR6X, 2*16pin and higher frequency.
But no one knows whether it will become an actual product. Because the test board of AD102 has more than two 16pin connectors, so everything is possible.

Today’s round of rumors comes from kopite7kimi on Twitter, who is a well-known tipster in the PC hardware space, with a good track record when it comes to Nvidia predictions. This time, kopite7kimi talked about Nvidia allegedly preparing a graphics card that utilizes the full AD102 GPU.

The GPU, aside from the enormous 900-watt power draw, would have plenty of memory to match. Kopite7kimi pointed toward 48GB of GDDR6X memory with a 24Gbps bandwidth. The frequency would also be higher than the base RTX 4090, of course, but the leaker didn’t give any figures as to that. The GPU would also allegedly feature a dual 16-pin design.

These specifications put the rumored GPU far above what we’ve heard of the flagship RTX 4090 so far. Multiple sources now allude to the RTX 4090 having a 600-watt power requirement as well as 24GB memory. This strongly points to Nvidia making this 900-watt/48GB memory version a separate GPU. It could be a future RTX 4090 Ti, although that’s a pretty steep jump when compared to the current generation of GPUs.

After all, the gap between the RTX 3090 and the RTX 3090 Ti is nowhere near as big. In terms of performance, there is an increase in favor of the RTX 3090 Ti, but it comes at a much-increased power draw. If Nvidia isn’t turning the new monstrous GPU into an RTX 4090 Ti, it could be a TITAN graphics card instead — something Nvidia didn’t revisit in the current generation of GPUs.

RTX 4080 will use AD103 chips, build with 16G GDDR6X, have a similar TGP to GA102.
RTX 4070 will use AD104 chips, build with 12G GDDR6, 300W.
Both of them haven't started testing yet, but soon do them.

Aside from talking about the rumored RTX 4090 Ti, kopite7kimi confirmed some of the specifications of the RTX 4080 and RTX 4070. According to them, each model will feature a different GPU. The RTX 4080 would use the AD103 GPU with 16GB of GDDR6X memory and a similar TGP to the current-gen GA102. Meanwhile, the RTX 4070 would use the AD102 chip with 12GB of GDDR6 memory and a 300-watt power requirement. The GPUs haven’t entered the testing phase yet, but it’s likely to happen soon.

Nvidia’s next generation of graphics cards, dubbed Ada Lovelace, is set to release later this year. Until Nvidia officially confirms the specifications and models that it’s going to launch, everything is just speculation — but the little we do know seems pretty exciting.

Even Nvidia’s partners don’t believe in the new RTX 4060 Ti
RTX 4060 Ti sitting on a pink background.

Nvidia's RTX 4060 Ti 16GB is reportedly just days away from launch, but rumor has it that there may not be a lot of GPUs to choose from. This isn't a sign of another dreadful GPU shortage, though. It's more that the RTX 4060 Ti has very little chance to rank high among the best graphics cards you can buy.

We've just recently seen the release of the RTX 4060, but Nvidia still has another card up its sleeve -- a clone of the existing RTX 4060 Ti that comes equipped with twice the VRAM. However, due to certain factors, the GPU might be doomed to a life of subpar sales and unsatisfying benchmark results.

Nvidia may have finally fixed its melting power connectors
The RTX 4070 graphics card on a pink background.

The 12VHPWR connector used in some of Nvidia's best graphics cards works well for most people -- but not for everyone. There have been reports of the connector melting inside the case, rendering the GPU unusable.

Nvidia seems to have learned from this experience, though. As it turns out, the Founders Edition of the RTX 4070 is no longer using 12VHPWR. Will the change be the remedy to these problems?

This mysterious Nvidia GPU is an absolute monstrosity — and we just got another look
Two Nvidia GPUs side by side.

The beast is back. Several new photos of what appears to be a quad-slot Nvidia GPU emerged today, revealing a monstrous prototype that's still yet to receive a name. In this iteration, it's more of a cooler than a GPU, as it doesn't appear to have a PCB.

Today's leak brings a lot of questions about what could one day be Nvidia's best GPU ever. Is Nvidia really working on a Titan GPU, or is this the RTX 4090 Ti?
