NVIDIA is developing the GeForce RTX 3070 Max-P and Max-Q with 8 GB and 16 GB of VRAM; GA106M for the RTX 3060 Max-P and Max-Q
In October, two PCI IDs relating to the GeForce RTX 3070 mobile and RTX 3070 Max-Q were added to the PCI ID Repository. Both lines stated that the cards were based on the GA104M GPU, having been assigned the IDs 249c and 249d. The PCI ID repository has since been updated though, revealing more details about NVIDIA's upcoming RTX 30 mobile product stack.
According to the references, NVIDIA has an 8 GB and 16 GB version of the RTX 3070 mobile in development. Incidentally, a recent leak by South African retailer Pinnacle also confirmed that OEMs would be pairing the 8 GB version with AMD's upcoming Ryzen 9 5900HX APU. It is unclear if NVIDIA is planning to release Max-P and Max-Q cards with 8 GB and 16 GB of VRAM, but the PCI ID repository contains four IDs referring to RTX 3070 mobile SKUs.
The same repository also contains a line for ID 2520, which refers to the RTX 3060 mobile and a Max-Q variant thereof. Again, Pinnacle already showed that NVIDIA is working on mobile versions of the RTX 3060, but the PCI ID repository adds that these cards will be built on a GA106M GPU.
NVIDIA is expected to release Max-P and Max-Q versions of the RTX 3080 too, so there should be plenty of RTX 30 mobile cards from which to choose early next year. If there are 8 GB and 16 GB versions of the RTX 3070 Max-P and Max-Q, then we could be looking at up to eight RTX 30 series cards. While four versions of the RTX 3070 seems excessive, NVIDIA already offers a tonne of mobile graphics cards SKUs to OEMs, so we would not rule it out yet.
