DirectML – Xbox Series X supports Machine Learning for games with DirectML, a component of DirectX. DirectML leverages unprecedented hardware performance in a console, benefiting from over 24 TFLOPS of 16-bit float performance and over 97 TOPS (trillion operations per second) of 4-bit integer performance on Xbox Series X. Machine Learning can improve a wide range of areas, such as making NPCs much smarter, providing vastly more lifelike animation, and greatly improving visual quality.
DirectStorage – DirectStorage is an all new I/O system designed specifically for gaming to unleash the full performance of the SSD and hardware decompression. It is one of the components that comprise the Xbox Velocity Architecture. Modern games perform asset streaming in the background to continuously load the next parts of the world while you play, and DirectStorage can reduce the CPU overhead for these I/O operations from multiple cores to taking just a small fraction of a single core; thereby freeing considerable CPU power for the game to spend on areas like better physics or more NPCs in a scene. This newest member of the DirectX family is being introduced with Xbox Series X and we plan to bring it to Windows as well.
GPU Work Creation – Xbox Series X adds hardware, firmware and shader compiler support for GPU work creation that provides powerful capabilities for the GPU to efficiently handle new workloads without any CPU assistance. This provides more flexibility and performance for developers to deliver their graphics visions.
Hardware Accelerated DirectX Raytracing (DXR) – From improved lighting, shadows and reflections as well as more realistic acoustics and spatial audio, raytracing enables developers to create more physically accurate worlds. For the very first time in a game console, Xbox Series X includes support for high performance, hardware accelerated raytracing. Xbox Series X uses a custom-designed GPU leveraging the latest innovation from our partners at AMD and built in collaboration with the same team who developed DirectX Raytracing. Developers will be able to deliver incredibly immersive visual and audio experiences using the same techniques on PC and beyond.
Hardware Decompression – Hardware decompression is a dedicated hardware component introduced with Xbox Series X to allow games to consume as little space as possible on the SSD while eliminating all CPU overhead typically associated with run-time decompression. It reduces the software overhead of decompression when operating at full SSD performance from more than three CPU cores to zero – thereby freeing considerable CPU power for the game to spend on areas like better gameplay and improved framerates. Hardware decompression is one of the components of the Xbox Velocity Architecture.
Intelligent Delivery – Microsoft's developer facing technology to reduce the size of game installs. Intelligent Delivery empowers developers to only install the pieces of the game you need, thereby minimizing the amount of content that needs to be installed or downloaded to the SSD.
Optimized for Xbox Series X – Games built using the Xbox Series X development kit and designed to take advantage of the unique capabilities of the Xbox Series X. These include new titles built natively using the Xbox Series X development environment as well as previously released titles that have been rebuilt specifically for Xbox Series X. They will showcase unparalleled load-times, visuals, responsiveness and framerates up to 120 fps.
RDNA 2 – The custom designed processor in the Xbox Series X leverages RDNA 2, the latest next generation graphics architecture from our partners at AMD. RDNA 2 provides a significant advancement in performance and efficiency as well as next generation graphics features such as hardware accelerated raytracing and variable rate shading.
Sampler Feedback Streaming (SFS) – A component of the Xbox Velocity Architecture, SFS is a feature of the Xbox Series X hardware that allows games to load into memory, with fine granularity, only the portions of textures that the GPU needs for a scene, as it needs it. This enables far better memory utilization for textures, which is important given that every 4K texture consumes 8MB of memory. Because it avoids the wastage of loading into memory the portions of textures that are never needed, it is an effective 2x or 3x (or higher) multiplier on both amount of physical memory and SSD performance.
Xbox Velocity Architecture – The Xbox Velocity Architecture is the new architecture we've created for the Xbox Series X to unlock new capabilities never-before seen in console development. It consists of four components: our custom NVMe SSD, a dedicated hardware decompression block, the all new DirectStorage API, and Sampler Feedback Streaming (SFS). This combination of custom hardware and deep software integration allows developers to radically improve asset streaming and effectively multiply available memory. It will enable richer and more dynamic living worlds unlike anything ever seen before. It also effectively eliminates loading times, and makes fast travel systems just that: fast.
Zen 2 – The custom designed processor in the Xbox Series X leverages AMD's latest Zen 2 CPU architecture. Zen 2 provides a significant advancement in CPU performance delivering more than 4 times the performance of an Xbox One X.
