Revealed: Improved Energy Performance in New Xbox Series X Models

Recent updates to the Xbox Series X lineup suggest improved energy efficiency in the latest models, as revealed in a detailed teardown.

A 16-minute video breakdown of the new Xbox Series X consoles highlights significant changes, including a smaller system-on-a-chip (SoC) and better energy performance. Both the 2TB version and the digital-only 1TB model now feature a redesigned motherboard, with the chip size reduced to 6 nanometers.

The cooling system has also been revamped, replacing the vapor chamber from the original 1TB model with a copper heat pipe design, a common solution in devices like this. While the change may not have a noticeable impact on most users, both models show a slight improvement in energy efficiency.

The previous Xbox Series X consumed 167 watts during gameplay, but the digital-only version now uses 156 watts, and the 2TB model drops further to 151 watts. In standby mode, the 2TB model consumes 51 watts, while the digital-only variant uses just 38 watts—an improvement over the original's 61 watts in idle mode.

While these changes may seem modest, they indicate a trend toward greater energy efficiency over time. Additionally, this shift could offer long-term cost savings for the company, as increased production efficiency may come into play as the Series X continues its lifecycle.
