If they go with 12GB total then the it would have to be on a 96-bit or 192-bit bus. If they go with 12GB, knowing Nintendo, they'd opt for the 96-bit bus. I can't see them going with the wider option. Depending on whether they use the slower or faster speed LPDDR5 already spec'd for Orin, it would leave the system with between 51GB/s to 75.6GB/s of bandwidth. Memory bandwidth was the biggest Achilles' heel of the Switch. I'm hoping that is addressed on the consoles next iteration. |
It doesn't have to be a 96-bit bus in order to have 12GB of RAM. If the RAM is 32bit then you could have 2x4GB and 2x2GB on a 128-bit bus. In addition, a 192-bit bus would allow for reduced clock speeds without sacrificing too much bandwidth. That would also allow for 4x2GB and 2x1GB, which is how I think the Switch will be set up (with the 2x1GB being reserved for OS functions).
That said, all of this being true in addition to what else has been listed paints Switch 2 out to be much more expensive than I think Nintendo would allow.
