The description on that page is quite vague, “With up to AMD Radeon™ 890M”, with no further specificity. I suppose the most expensive model is the 890M, but what about the other two?
Hi, great question! I’ve been there before as I transitioned from the Steam Deck. I hold a 7840U mainboard on my 13 right now as an FYI.
I use Notebookcheck.net as a reference for the chips and look to their graphics section for specifics to the integrated GPUs in the mainboard CPUs compared to dedicated GPUs.
