It’s extremely impressive.
We’ve heard so much about how powerful the Xbox One X is- but ultimately, the best demonstration of that is seeing it in action for ourselves, and understanding how it is working behind the scenes, if we cant. Most gamers can’t, of course- but the fine folks at Digital Foundry can, and they posted a lengthy video explaining how games perform on the Xbox One X versus the existing Xbox One S.
According to the analysis, Forza 7 uses up 77.8% of the GPU power in the original Xbox One to go up to 1080p and 77fps (the final game is probably going to be locked at 60fps). In contrast, the same game running in native 4K on Xbox One X uses 65.9% GPU power for 91fps (although, again, the framerate will probably be locked in the final release).
That resolution bump, framerate boost, and reduction in overall GPU usage should demonstrate by itself how much stronger the Xbox One X is- and it’s not just Forza 7, either. Gears 4 is at 84.1% GPU utilization on the original Xbox One for its 30fps frame-rate target at 1080p. On the other hand, running at 4K on Xbox One X, the game uses 78.1% of the GPU power. It’s kind of nuts.
Hopefully, then, this power is actually utilized in full by third party developers when the Xbox One X launches later this year.
