A3B-35B is better suited for laptops with enough VRAM/RAM. This dense model however will be bandwidth limited on most cards. The 5090RTX mobile sits at 896GB/s, as opposed to the 1.8TB/s of the 5090 desktop and most mobile chips have way smaller bandwith than that, so speeds won't be incredible across the board like with Desktop computers.
