According to the latest GPU rumour, Nvidia’s RTX 4080 graphics card may be more power-hungry than expected.
Kopite7kimi claims the 16GB of GDDR6X video memory will be 23Gbps, and the graphics card’s power utilisation is now 340W.
Kopite7kimi predicted Nvidia to employ 21Gbps GDDR6X VRAM and 320W TBP.
Leaker still believes RTX 4080 will have 9,728 CUDA Cores. Season everything as usual.
While the power consumption has supposedly been bumped to 340W from 320W, both figures are way down from earlier rumours about 420W. We’ve gone from a power-hungry xx80 GPU to a much gentler beast.
Nvidia is still developing and testing these Lovelace GPUs, possibly making modest adjustments regularly. When the dip to 320W was leaked, we couldn’t believe it was so much lower (from well over 400W as mentioned).
Perhaps Nvidia is calibrating the 4080 to differentiate it from the 4070 – they can’t be too close in raw oomph, and the 4070 is shaping out to be a wonderful card – and this power spike is part of assuring excellent enough performance with the 4080 versus the 4070. (faster VRAM will obviously help that cause, too).
All of this is educated guesswork, but as the RTX 4000 launch approaches, these specs should be more accurate. It looks like the RTX 4080 won’t be as power-hungry as rumoured.
Nvidia’s next-gen graphics cards are planned to ship in October, however the 4080 and 4070 may be delayed to allow current-gen RTX 3000 stock to sell through. This could be a problem for Nvidia, but we hope to see the RTX 4080 in November, after the RTX 4090. (in October).
If the RTX 4080 uses 23Gbps VRAM, can we assume the RTX 4090 will too? When queried about this on Twitter, Kopite7kimi said, “I don’t know.” Hopefully.”
