The console's form is designed to be unobtrusive and minimalistic. It is approximately 6 inches (15 cm) wide and deep, and 12 inches (30 cm) tall; 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 the optical media slot. The top of the unit is a single powerful fan. Xbox head Phil Spencer said that the Xbox Series X was as quiet as the Xbox One X. Microsoft stated that the console CPU will be four times as powerful as Xbox One X; it features AMD's Zen 2 CPU architecture and RDNA graphics architecture, a custom-designed solid state drive, GDDR6 SDRAM, and support for real-time ray-tracing, up to 120 frames per second rendering, and 8K resolution. Microsoft has also promoted "auto low-latency mode," "Variable Rate Shading," and "dynamic latency input" technology—a new dynamic latency input pathway that allows developers to incorporate potential controller lag into their games and improve responsiveness.
