Physical Size/Color
The first and most obvious difference between Xbox Series X and S is their physical appearance. They both have a minimalist design, but Series X is predominantly black whereas Series S is predominantly white with a large — arguably gaudy — black circle on it.
There’s also a considerable difference in size between the two new Xbox consoles. Series S is miraculously smaller than the already quite small Xbox One S and it’s touted as being 60 percent smaller than Series X.
This is unlikely to be a dealbreaker for most people, but if you have limited space, then it’s something to keep in mind. Still, Series X is only 1 mm taller than the Xbox One X. If you’re looking to upgrade from the One X to the Series X, then you should be fine when it comes to space.
