So, Microsoft's new Xbox Series X and S models are starting to roll out today (with more regions to follow), and while they look and perform similarly to the existing models, a new teardown video is showing some noticeable differences on the inside.

Up above, tech YouTuber Austin Evans has taken a look at the internals of Microsoft's two new Xbox Series X models compared to the 2020 original , skipping over Xbox Series S for now. While all the Series X models share huge similarities, the processor, motherboard and heatsink have changed in the new models - something which Xbox hadn't disclosed before release.

The video goes on to do some quick testing, including for noise levels, heat production and power usage, and the new models are more efficient overall, which shouldn't be a huge surprise. Still, it's nice to see - especially in the power department where the new versions will draw a chunk less power from your outlets.

If you're interested in the nitty gritty of this sort of thing, the video up above is certainly worth a watch. Hopefully we see something similar for the new Xbox Series S model soon, but for now, know that if you're picking up one of these Xbox Series X refreshes, you're getting a more efficient machine overall.

Are you surprised to see as many internal changes here? Tell us down in the comments below.
