More than I could name because AI  can be trained to do a lot but for the lower power Xbox it could be used for super resolution upscaling  from 1080P to 4K  & for raytracing & volume rendering it can be used to denoise the image .   then there is gameplay & voice commends ,  think about having a game with a very large data base of responses & able have somewhat of an idea of what you're saying & quickly go through it's data base & respond to you like Alexa.  
I really don't have a clue what RCC is so I'm clueless as to how that would work but I do know that the person that wrote this up   used TFLOP  instead of TFLOPS  when talking about 1 TFLOPS as if they didn't know that the s is for seconds.    so I wouldn't read too much into this
