Nvidia could create a next-gen GPU that’s even more power-hungry than previous rumors suggested, and that’s really saying something, as TDP speculation has already reached pretty ridiculous levels in the past.
The theory, as circulated by kopite7kimi on Twitter, is that with the most powerful incoming Lovelace GPU, known as the AD102, Nvidia could produce a ‘full’ monster of a high-end graphics card that could draw 900W of power (yes, you read that right).
In fact, there is another complete AD102 SKU with 900W TGP, 48G 24Gbps GDDR6X, 2*16 pin and higher frequency. But no one knows if it will become an actual product. Because the AD102 breadboard has more than two 16-pin connectors, so anything is possible.April 27, 2022
Now the first thing to note here is that this is exactly what a hardware leaker heard, and furthermore kopite7kimi states that it is unknown if this allegedly fully unleashed version of the AD102 will ever be turned into a real product. In other words, while Nvidia is supposed to tinker with such a GPU, it may never leave the testing or prototyping stages.
If so, however, the theory is that on top of that 900W power draw, it’ll be absolutely jam-packed with VRAM – 48GB of GDDR6X running at 24Gbps, rumored to be.
Analysis: titanic power struggle?
The AD102 chip is expected to power Nvidia’s RTX 4090 and RTX 4080, and indeed, we’ve already heard it’s currently in testing. At first glance, that 900W power consumption seems absolutely staggering – remember, even the RTX 3090 Ti only draws half of that (at 450W, which is still very heavy use as we have highlighted in our review).
This would therefore be equivalent to a pair RTX 3090 Ti graphics cards, in theory. But then we’ve heard rumors of around 800W or 850W power consumption before, even though that was a few months ago now, and more recent word from the vine floated numbers more at the 600 W mark (which is always a big ask, listen).
If there was a 900W version of the AD102 in (graphics) cards – and that’s a big fat if – then it would surely not be a consumer model. Perhaps this variant in review is a potential return of the Titan RTX with Lovelace? (There was no Titan model for Ampere; the last one produced by Nvidia was with Turing or RTX 2000).
Either way, if realized, this will surely be a heavy GPU targeted at pros, not aimed at consumers with that kind of power consumption, which would require a huge power supply, without talk about some sort of ridiculous cooling setup to deal with that kind of thing. heat in a PC case. (And indeed, we can only guess what the price might be, but it would be untenably beyond the average PC enthusiast’s build fund, of course – and that’s before we consider the undoubted and unwanted contribution that this would bring to the electricity bill).
We’d be treating this rumor with extreme caution at this time, and best to watch this space and see if any more speculation arises about what could be a new Titan GPU.
