Xbox Series S/Lockhart Has 7.5 GB of Usable RAM, Games Will Run At 1080p Or 1440p – Report

Further supposed details have arrived for the Xbox Series S/Lockhart. The Verge has had sources confirm that the Xbox Series X dev kit has the Lockhart model. The publication also provided unconfirmed information on performance.

The rumors are increasing: Microsoft is apparently pursuing the goal of launching a second next-gen console alongside the Xbox Series X. According to the previous information, the Xbox Series S (codenamed Lockhart) will be marketed as a cheaper and less powerful entry-level console. You can probably run games with up to 1440p at a great price.


In the meantime, the technical details could be determined. A recently leaked Microsoft document published on Twitter includes references to the Lockhart console. In addition, The Verge was able to find sources familiar with Microsoft’s Xbox plans. These confirmed that the special Lockhart model is part of the Xbox Series X developer kit.

But with only 4 teraflops? According to the publication, the devkit gives developers the option to activate a special Lockhart model that includes a profile of the performance Microsoft wants to achieve with the second console. The Verge assumes that 7.5 GB of usable RAM, a slightly underclocked CPU speed and about 4 teraflops of GPU performance are used.

For comparison: The Xbox Series X has 13.5 GB of usable RAM and is aimed at 12 Teraflops GPU performance. The Xbox One X already has 6 Teraflops and the PS5 has up to 10.28 Teraflops GPU performance, which makes the alleged 4 Teraflops of the Xbox Series S look quite outdated.


Ultimately, the developers should be able to use the Lockhart model to test their games with the lower performance profile and to be able to carry out validation checks. Microsoft is expected to position the Lockhart console for 1080p or 1440p games.

The Xbox Series S has not yet been announced. Microsoft may be waiting until the Xbox Series X and PS5 prices have been officially made, so that the “S” model can be advertised with a significantly lower price.
