The latest Xbox Series X is available for purchase; a new discless model available in a fresh white 1TB option as well as a 2TB Galaxy Black Special Edition (with an optical drive). The lack of an optical drive and new white paintwork on the 1TB Xbox Series X are obvious, but under the hood of both new variants are more changes. Microsoft has shrunk the system-on-a-chip to 6nm, completely redesigned the motherboard, and changed the cooling system for the console.
