The PlayStation 5 vs. the Xbox Series X: Which is more powerful?

We take a dive into the specs to see who's got the more impressive hardware.

The next generation of consoles is coming, with plenty of emphasis on how much power these things have — the better to render modern graphics. Last week we got a look at what's inside Microsoft's Xbox Series X, and today we're finally seeing what's under the hood with the PlayStation 5. As usual, we've lined up their specs for a side-by-side comparison, though for a final verdict we'd wait to see what games each system has lined up and Engadget's full review when both systems launch later this year.
