How many teraflops of GPU computing power did the Xbox One X advertise?

The Xbox One X advertised 6 teraflops of GPU computing power.

Microsoft unveiled the Xbox One X in 2017 as the most powerful Xbox console at that time. Its custom graphics processor used AMD graphics technology and delivered substantially more theoretical compute performance than the original Xbox One and Xbox One S. The extra power supported higher-resolution rendering, improved texture detail, and steadier performance in enhanced games.

The figure is a theoretical floating-point performance measure, not a guarantee that every game runs at a fixed resolution or frame rate. Actual results depend on software design, dynamic resolution, visual settings, and developer optimization.

The Xbox One X is sometimes confused with the Xbox Series X, whose GPU is rated at 12 teraflops. The Xbox One X remained part of the Xbox One family and played Xbox One software, while the Series X began a later generation.
