New information about the GeForce RTX 4080 SUPER has emerged online, a few days after Benchlife claimed to have obtained details about the unreleased graphics card. In summary, the website alleged that NVIDIA had informed its partners of a new AD102-derived card with 20 GB of GDDR6X VRAM. Subsequently, @kopite7kimi disagreed, instead putting forth the idea that the RTX 4080 and RTX 4080 SUPER could be linked like the RTX 2080 and RTX 2080 SUPER.
In other words, @kopite7kimi appears to be suggesting that the RTX 4080 SUPER will sport a full AD103 GPU with faster VRAM and a higher TDP. While the graphics card's specifications remain a mystery for now, references to an unreleased model have turned up on the PCI ID Repository. For context, users like T4CFantasy update the repository based on early GPU BIOS builds, and GPU-Z validations; NVIDIA and its partners do not add to it directly.
Nonetheless, the PCI ID Repository has served as an early sighting of a future graphics card previously. As the image below shows, there is now a PCI ID for '2703', an AD103-based card that is linked to the marketing name 'GeForce RTX 4080 SUPER'. For reference, '2703' is adjacent to the desktop version of the GeForce RTX 4080, which NVIDIA assigned '2704'.
Thus, it would seem that the GeForce RTX 4080 SUPER is also a desktop card, rather than a sign of an upcoming laptop refresh. It is worth noting that NVIDIA does not always bring to market graphics cards that it adds to early GPU BIOSes. However, it is likely that the company is developing the GeForce RTX 4080 SUPER with the AD103 for now and not the AD102.
