Nice video by Brad Sams that explains the technique with Xbox and AMD

From what I perceive there are going to be particular Xbox chips which are going to be within the subsequent console, handheld and sure PCs.

It sounds just like the chip might be able to full backwards compatibility with all of your Xbox video games so it is possible for you to to natively play Xbox video games on these Xbox PCs(this branding makes much more sense now).

Any oem will be capable of purchase these chips and make their very own Xbox machine.

This explains why there's an Xbox emblem on the Z2 Excessive. That is my very own hypothesis however I feel in some unspecified time in the future after launch the Xbox Ally X would be the first machine able to native Xbox console video games.
