It's been almost a full week since Xbox One X launched around the globe, and Microsoft's powerful new console is off to a strong start, particularly in the UK. The system has sold more than 80,000 units in the region during its first seven days on the market.

Notably, that makes Xbox One X's first-week sales the same as Nintendo Switch's when it launched back it March. It's also significantly ahead of PS4 Pro's launch-week sales in the UK; Sony's console moved roughly 50,000 units during its first week last November and took four weeks to hit 80,000 sales.
