The sleek monolithic design of Xbox Series X is the result of combining hardware and software innovations with intentional engineering to achieve the zenith of speed and performance.box Series X
Xbox head Phil Spencer stated that Microsoft was prioritizing high frame rates and faster load times as a priority over higher resolutions, which the Series X achieves via the better-matched capabilities of the CPU and GPU.box Series X
The Xbox Series X is powered by a custom 7 nm AMD Zen 2 CPU with eight cores running at a nominal 3.8 GHz, or when simultaneous multithreading (SMT) is used, at 3.6 GHz. One CPU core is dedicated to the underlying operating system. The graphics processing unit is also a custom unit based on AMD’s RDNA 2 graphics architecture. It has a total of 56 compute units (CUs) with 3584 cores, with 52 CUs and 3328 cores enabled, and will be running at a fixed 1.825 GHz. This unit is capable of 12 teraflops of computational power. The unit ships with 16GB of GDDR6 SDRAM, with 10GB running at 560GB/s primarily to be used with the graphics system and the other 6GB at 336GB/s to be used for the other computing functions. After accounting for the system software, approximately 13.5GB of memory will be available for games and other applications, with the system software only drawing from the slower pool. The Xbox Series X target performance is to render games at 4K resolution at 60 frames per second, with the console being about four times as powerful as the Xbox One X. The Series X can support up to 120 frames per second, and can render up to 8K resolution.box Series X
The Xbox Series X’s console form is designed to be unobtrusive and minimalistic. It has a 15.1 cm × 15.1 cm (5.9 in × 5.9 in) footprint and is 30.1 cm (11.9 in) high and weighs 4.45 kg (9.8 lb); while configured in this vertical orientation, the unit can also be used on its side. Its forward-facing features present only the main power button and an Ultra HD Blu-ray drive. The top of the unit is a single powerful fan. Spencer stated that the console is as quiet as Xbox One X. The Series X includes an HDMI 2.1 output, the storage expansion slot, three USB 3.2 ports, and an ethernet port. The console does not include an infrared blaster or HDMI pass-through like the Xbox One line, supporting HDMI-CEC instead. An earlier leak had suggested a TOSLINK port for digital audio, but this was eliminated in the final design. However, the console still has an IR receiver integrated into its controller pairing button next to the front USB port.
