The upcoming Nvidia GeForce RTX 4080 Super is set to use the same AD103 GPU as the existing RTX 4080, according to a fresh RTX 4000 Super leak. With the RTX 4080 only using some of the AD103 GPU, this leak suggests we can expect the RTX 4080 Super to use all or most of the same GPU, unlocking up to 5% extra performance.
The new Nvidia RTX 4080 Super specs leak comes via a website called PCI ID repository. This resource stores a list of all known PCI device IDs, with contributors sometimes adding rumored or leaked entries, and one such contributor has just added an entry that simply says “Name: AD103 [GeForce RTX 4080 SUPER]”.
While this is far from a nailed-on certainty of a source, the suggestion that an RTX 4080 Super would use a fully-unlocked version of the AD103 is not just plausible but downright expected. After all, while it’s possible an RTX 4080 Super could be made by using feature-reduced versions of the much larger AD102 GPUs that are used in the RTX 4090, it seems unlikely Nvidia would have a large stockpile of RTX 4090 chips with enough defects to warrant being used in a significantly downgraded graphics card.
As for the specs that would result from using a fully or nearly fully enabled AD103 GPU, a fully-enabled AD103 chip has six Graphics Processing Clusters (GPCs) with 12 Streaming Multiprocessors (SMs) each, and another GPC that contains a further eight SMs. As such, if all the parts were enabled you’d get a total of 10,240 stream processors / CUDA cores. The current RTX 4080 has four of the chip’s SMs disabled, though, giving you 9,728 stream processors.
If that is all the increase we get, the RTX 4080 Super would only be providing a 5% performance improvement, which would be a bit underwhelming. However, it’s possible Nvidia will bolster performance with higher clock speeds and more VRAM, with the latter already being a rumored upgrade for the upcoming graphics card.

But, the pattern of evidence is building suggesting the card will be called the RTX 4080 Super and not the RTX 4080 Ti, for instance.
