Xbox Series X vs PS5: What we know so far

By Heidi Nicholas,
Earlier this week, Xbox shared new spec details about their Xbox Series X, as well as a first look at the new wireless controller to be included with it when it releases in the Holiday period later this year. Now, just days later, Sony has released their first proper look at the PlayStation 5, their own next-gen console releasing alongside, and in direct competition with, the Xbox Series X. Here's what we know so far.

As noted by Eurogamer, we now have the initial specs for the PS5, contrasted with the Xbox Series X specs as laid out in an Xbox Wire post.

Cerny claims an 100% load speed improvement over the PS4, and some impressive technology that allows performance on the components to allegedly be unaffected by ambient temperature. Cerny also claims that the smaller and more agile GPU will deliver higher performance across the board, something that can't be defined by TFLOPs alone. Digital Foundry, reporting for Eurogamer, speculate that the PS5's approach to power may put more of an onus on the developer to optimise for it compared to the Xbox Series X.

This is everything revealed so far, but PlayStation has promised more news on games later in the year. We have a roundup of all Xbox Series X news, including the Xbox Series X specs, so be sure to check those out if you'd like to know more.
