Anandtech posted a review on the Xbox Series X
A quote from the article:
What makes a console generation? The lines have been blurred recently. We can state that the Xbox Series X, and its less-powerful sibling, the Series S, are the next generation consoles from Microsoft. But how do you define the generation? Just three years ago, Microsoft launched the Xbox One X, the most powerful console in the market, but also with full compatibility with all Xbox One games and accessories. With multiple tiers of consoles and mid-generation refreshes that were significantly more powerful than their predecessors – and in some cases, their successors – the generational lines have never been this blurred before.Xbox Series X Review
None the less, the time for a “proper” next generation console has finally arrived, and Microsoft is fully embracing its tiered hardware strategy. To that end, Microsoft is launching not one, but two consoles, with the Xbox Series X, and the Xbox Series S, each targeting a difference slice of the console market both in performance and price. Launching on November 10, 2020, the new Xboxes bring some serious performance upgrades, new designs, and backwards compatibility for not only the Xbox One, but also a large swath of Xbox 360 games and even a good lineup of games from the original 2001 Xbox. The generational lines have never been this blurred before, but for Microsoft the big picture is clear: it’s all Xbox.
