A performance upgrade seems to be pending for gaming notebooks in the near future: According to rumor cooks Nvidia is working on a more powerful mobile GPU that is above the previous flagship GeForce RTX 3080.
The latter graphics chip has 6144 shader cores and is based on the GA104, while the GA103 with more shader cores is to be used for the new top model: There are rumors of 7680 or even more cores. The new graphics chip should carry the PCI ID 10de: 2420 and address 16 GB of GDDR6 memory via a 256-bit interface.
While the key technical data would already be outlined very narrowly, there is little tangible information about the potential name. A mobile GeForce RTX 3090 would be conceivable as well as a mobile GeForce RTX 3080 Ti. In the data sheet of a Lenovo notebook, the previously unknown names GeForce RTX 3080 Super and GeForce RTX 3070 Super, which also match the GA103 rumors, have already been used. The latter model would then be a slimmed-down GA103 variant (PCI-ID 10de: 24a0) that fits between the well-known RTX 3080 and RTX 3070 mobile models.
It is also unclear whether Nvidia is tweaking the permissible waste heat classes with the GA103 newbies. The notebook manufacturers have several options for each GPU model, which has confusing and drastic effects: A GeForce RTX 3080 with a minimum of 80 watts is usually slower than a GeForce RTX 3070 that runs with the intended maximum of 125 watts.
Official light in the dark will probably not come until next year: Nvidia is likely to unveil the mobile GA103 GPUs in January 2022 at the technology fair CES, at which the launches of new CPU generations from AMD (Rembrangt alias Ryzen 6000) and Intel (Alder Lake alias twelfth Core i generation) are expected. And gaming notebooks with the new components will probably only be available for purchase in spring 2022.
