Evidence pointing towards a second next-generation Xbox continues to mount, this time with wording in the latest Game Development Kit SDK notes mentioning profiling modes for Xbox Lockhart.

Lockhart is a name that has been attributed to the other next-gen Xbox for some time now, stemming from the Anaconda and Lockhart project titles given to hardware under the banner of Project Scarlett. Anaconda would go on to be named the Xbox Series X, which Microsoft formally revealed in December last year. But since then the company has made no mention of a second SKU--at least not officially.

The latest GDK released to Xbox developers, as reported by The Verge, does make specific mention of Lockhart. It lays out a new profiling mode that will allow existing dev kits to mimic the performance conditions of the reportedly lower-powered consoles, including a slightly reduced CPU clock speed, less available RAM (about 7.5GB only), and significantly less GPU power (around four teraflops, as opposed to the 12 teraflops in the Xbox Series X). What that equates to is a testing profile that features the same SSD speeds and similar CPU performance but far less headroom for high resolution gaming.
