Before starting, let us specify that we must take this news rumor with large tweezers. Indeed, even on the RTX 3000s of NVIDIA there have been several rumors of variants with different memory configurations. How not to mention in this case the RTX 3080 of which there have been rumors of 16 and 20 GB versions. Some were produced as a prototype like the 20 GB of which there are photos, but which was never for as marketed.
To come back to the subject. It is on Twitter that @Zed_Wang announces that the NVIDIA RTX 4080 graphics card would have two variants with two memory configurations. PCBs would be much different. Concretely, the first version would use a 10-layer PCB for the version of the RTX 4080 with 12 GB of memory GDDR6X and the second version a 12-layer PCB for the version in 16 GB GDDR6X. Note that to this tweet, 3DCenter.org responds that the PCB of the RTX 4080 12G could in fact be an RTX 4070 due to a 192-bit bus. To which the leaker replies that he is sure it is an RTX 4080.
4080 12G GD6X 10layer PCB aic reference design
4080 16G GD6X 12layer PCB aic
4090 24G GD6X 14layer PCB aic reference design
note：4080 12G has a completely different pcb design from 4080 16G

For now, from what we know the GeForce RTX 4080 should feature a new AD103 GPU with 9,728 CUDA cores and a consumption of up to 340W. If NVIDIA really launched two variants of its card, it is likely that like the RTX 3080 10 and 12 GB, the launches will be staggered with the 12 GB first. The 16 GB could come later.
We take this opportunity to put you what could be the first photo of the card NVIDIA GeForce RTX 4080 Founders Edition. The typography of the reference has changed compared to the RTX 3000, but it corresponds perfectly to the new typo on the NVIDIA site for the RTX 4000. Again, it must be taken with tweezers, it could still be a prototype and final versions may have a different design.
Finally, let’s remember once again that you have to take all this with a grain of salt, the chameleon brand has a lot of projects and not everything is necessarily done afterwards.
