It’s not the same thing. The ROG Ally X is an AMD Z1 Extreme and the Xbox Ally X is an AMD Z2 Extreme. It’s not clear yet how well the Z2 Extreme performs in comparison to the Z1 Extreme.
The Phawx did some testing with the Legion Go 2 and their Z2 (non-extreme) performs worse than the ROG Ally X. -> https://www.youtube.com/watch?v=gVdOkbJ9Npo&pp=ygUVTGVnaW9uIEdvIDIgdGhlIHBoYXd4
My cautious expectation is that it will perform marginally better than the ROG Ally X, maybe be 10-15%, though I’m not touching anything Microsoft at this time in history.
I think this is a case, where there’s an engine that was developed for graphics cards, that epic thought were common when they created UE5. They expected that RT performance would not only increase in the highest pricing tier, but also in mid-range (as in $500 pricing range) to a degree, where all the lumen stuff would be trivial. But steam survey reveals that most people use X060, X050 and then some X070 class cards, where RT performance isn’t that great. https://store.steampowered.com/hwsurvey/videocard/
So IMO there are several issues:
The end result stays the same, we now play games that run so bad on current hardware, that everything now needs to be AI-upscaled with framegen and has this weird soft look that will look super dated at some point because RT isn’t there yet.
