Nvidia’s RTX 4080 graphics card may have a little more power consumption than previously stated, at least according to the latest nugget of the always-spinning GPU rumor mill.
VideoCardz (opens in new tab) noticed that Kopite7kimi, a prolific leaker on the Nvidia front, showed off new specs on Twitter for the next-gen Lovelace RTX 4080.
Let’s do some updates. RTX 4080PG136/139-SKU360AD103-300-A19728FP3216GB 23Gbps GDDR6X total card power 340WAugust 23, 2022
The alleged specs remain the same as last we heard from Kopite7kimi, except for a few key differences: the statement that the GDDR6X’s 16GB will be 23Gbps video memory, and that the graphics card’s power usage is now set at 340W.
Previously, the power usage (TBP or Total Board Power) was rumored to be 320W, and Kopite7kimi expected Nvidia to use 21Gbps GDDR6X VRAM.
The leaker still believes that the RTX 4080 will run with 9,728 CUDA Cores, just like before. Take it all with the usual bucket full of spices, naturally.
Analysis: Almost there with the final tweak?
While power consumption was reportedly bumped up to 340W instead of 320W, as per previous leaker speculation, keep in mind that both numbers are far below previous rumors that theorized around 420W or more. So we’ve gone from a seriously power-hungry GPU (for a model xx80) to a much more tame beast, however you look at it.
Of course, at this point, Nvidia is still actively developing these Lovelace GPUs and putting them through their final tests and paces, likely making small tweaks pretty consistently. So it’s no surprise to see power demands change a bit here, and indeed when the drop to 320W leaked out, we struggled to believe it would be reduced so heavily (from well over 400W, as mentioned).
Perhaps Nvidia is now tweaking the RTX 4080 to further differentiate it from the 4070 – they can’t be too close in terms of raw grunt, and mind you, the 4070 is apparently turning out to be a great card – and that power boost it’s all part of ensuring good enough performance with the 4080 versus the 4070 (faster VRAM will obviously help in this cause too).
This is all just an educated guess, naturally, but the good thing is as far as rumors go, as the RTX 4000’s launch approaches, these specs are likely to be more dialed in. as the RTX 4080 doesn’t go very heavy on power usage as was originally rumored.
The little fly in the launch ointment is that while Nvidia’s high-end graphics cards will launch worldwide in October, we don’t know if the RTX 4080 (and 4070) might not be delayed for some time to allow for next-gen RTX 3000 stock. current to sell. This could pose a thorny issue for Nvidia, potentially, but the hope is that we’ll see the RTX 4080 perhaps in November, following the launch of the initial Lovelace GPU that’s supposed to be the RTX 4090 (in October).
Speaking of the Lovelace flagship, if the RTX 4080 uses 23Gbps VRAM, can we assume the RTX 4090 will work too? This certainly makes sense, although Kopite7kimi, when asked about it on Twitter, sounded unsure, responding (opens in new tab): “I don’t know. I hope so.”
