Regardless of your hardware, you'll also need Windows 10 64-bit and DirectX 11 to play.
Larian said Baldur's Gate 3 "may be playable" on PCs below the new minimum requirement (but, I would guess, not below the old minimum), "but we believe this may hinder the player experience." I suspect it might, too.
The series S zen 2 8/16 core cpu @ 3.4/3.6ghz will far out perform the zen 1 4/8core @ 3.5ghz
So there shouldn't be an issue of CPU power esp as its the same as the ps5 and series x
The series S gpu will be a bit worse than the 5700xt in pure rasterization most likely but leaps and bounds better than an rx 480
Serie S gpu is rdna 2 20 CU @ 1.5ghz
R5700xt gpu is rdna 1 40CU @1.755ghz
Rx480 gpu is gcn 4 36CU @ 1.266ghz
I don't see anything here that would prevent split screen unless the 5700xt can't handle it either. But then again the 5700xt would compare favorably to the ps5 and series x
5700xt gpu is rdna 1 40CU @ 1.755ghz
Ps5 RDNA ? 36CU @ up to 2.23ghz
XSX RDNA 2 52CU @ 1.825ghz
The game is also designed to be played on 4GB of vram and 8 gig of system ram. But on a pc you need to account for all the windows over head.
I don't see where the major issue would come in at. They already did low quality texture work for the pc
