I think the 8K print on the XSX APU might not just be marketing. DirectML has flown under the radar for a year, because raytracing seemed like the bigger deal. But the Reddit leak from January 2019 mentions Microsoft AI. Using DirectML you could actually upscale a 4K image to 8K, like it has been proven to work for 1080p to 4K. Xbox Series X might actually be a full 8K console.

Forza Horizon 3 is shown at 15:41. This could be the real secret sauce Microsoft has for XSX. If they have DirectML upscaling to 8K in hardware on the APU, that propels the console to the equivalent of a 48 TF APU. It's absolutely crazy.
Similarly, the console could render raytracing at 1080p because of the huge performance impact and then simply use machine learning to reach 4K with much better and most of all faster results that could be achieved by using raytracing at 4k.
