Next-gen Xbox codenamed Anaconda to target 12 teraflops (Lockhart: 4TF), 16GB RAM (13GB for games, 3GB for the OS) and will also feature a NVMe SSD to drastically reduce load times

Information via Windows Central:

Microsoft is gearing up to reveal a two-pronged attack for next-gen consoles, complete with a more affordable SKU, dubbed "Lockhart," and a more beastly premium SKU, codenamed "Anaconda." We have no idea what the next-gen consoles will look like, or be officially named when the time comes, but we do now have a credible idea of what specs these systems are targeting.

Both Lockhart and Anaconda reportedly sport eight CPU cores targetting around 3.5GHz, with Anaconda reaching a bit higher per core than Lockhart. The relatively modest increase in clock speed over the previous-gen systems may seem mild, but vast improvements to caching, new silicon architecture, and other general bespoke, proprietary optimizations will see Anaconda perform anywhere up to four to five times better than the Xbox One X, if targets are met. We're told that at least Anaconda will guarantee 13GB of RAM for games, with 3GB on the OS a total of 16GB. The X, by comparison, offered a "maximum" of 9GB for games, which often varied based on what the OS was doing. Microsoft also said in its reveal video that the SSD could be used to throw in virtual RAM as necessary. Speaking of which.

One huge focus area for Lockhart and Anaconda is on NVMe SSD proprietary tech, which dramatically decreases load speeds, nigh-on eliminating loading completely. Games with load times anywhere up to a minute will be reduced to mere seconds as a result of these SSDs, and the inclusion of Project XCloud across all Xbox systems will allow you to start gaming via streaming while waiting for games to download locally. Next-gen is all about saving you time, increasing read speeds by gigabytes per second, while also providing cutting-edge visuals that will elevate games to all new heights.

Games with load times anywhere up to a minute will be reduced to mere seconds.

We've been told that while many games will function across generations, next-gen features such as ray tracing for dynamic reflections and the like will most probably be exclusive to Lockhart and Anaconda, requiring new APIs that come as part of Game Core OS (which is also part of the Windows Core OS effort we've been covering). That said, Scarlett will be able to run all previous-gen games that are available on Xbox One today, including backward compatible games as Microsoft has already announced.
