The Xbox Series S, also known as Lockhart, has yet to be announced, but some more details on its specs have emerged online.

According to a report from The Verge, the Xbox Series X devkit, codenamed Dante, comes with a special Lockhart profile. This profile provides a good indication of the console's specs, revealing 7.5 GB of usable RAM, a slightly underclocked CPU speed, and around 4 teraflops of GPU performance. With these specs, the console will target 1080p and 1440p gaming, unlike the Xbox Series X which will target 4K.
