The Verge has stumbled across a Microsoft Game Development Kit update from June 2020. It references multiple Project Scarlett consoles obviously alluding to the fact that there will be another console alongside the Xbox Series X. This has been known to be the Lockhart model (expected to be called Xbox Series S).
The Verge is reporting that there’s a Lockhart profiling mode in the Xbox Series X developer kit. This includes 7.5GB of ram (compared to the Xbox Series X 13.5GB of usable RAM), an underclocked CPU speed and around 4 teraflops of GPU performance (compared to the Xbox Series X 12 teraflops of GPU performance). The Xbox One X has 12GB of RAM and 6 teraflops.
It’s rumoured that the console will be targeting 1440p and 1080p gaming, but will have many of the same next-gen features that the Xbox Series X has (a fast SSD, the ability to swap between games on the fly). We’re expecting that we’ll see the announcement of Lockhart in August.
