The big Xbox Series X reveal had a lot of technical info to unpack. We already knew that the CPU and the GPU would be powered by AMD's Zen 2 and RDNA 2 architectures, respectively, but Microsoft introduced a lot of unexpected features, such as the so-called Xbox Velocity Architecture, which is comprised of four components: custom NVMe SSD, a dedicated hardware decompression block (to eliminate all overhead associated with real-time decompression), the all-new DirectStorage API (reportedly coming to PC, too, at some point), and Sampler Feedback Streaming (SFS). The latter, for instance, aims to greatly improve memory utilization for textures, therefore acting as a 2x or 3x multiplier for memory and SSD performance.

Other highlights of the Xbox Series X unveiling include DirectML support, powered by over 24 TFLOPS of 16-bit float performance and over 97 TOPS (trillion operations per second) of 4-bit integer performance on Microsoft's next-generation console. Machine learning will be used in a number of ways, from making NPCs much smarter to providing vastly more lifelike animation and greatly improving visual quality as a whole.
