Should you buy the Xbox Series S vs Xbox One S? These two Microsoft gaming consoles might have similar designs and similar names, but there are some significant differences between the two. What’s important to know up front is that the XBox Series S is the newer console of the two and capable of 1440p resolution, upscaled to 4K, 120fps and this includes graphical features, such as ray tracing. Granted it might not be as powerful as Microsoft's current flagship, that’s the Xbox Series X, but it’s still a next-gen console through and through.
