### Comment:
And I'm fairly certain they were in the generation before that.  AMD has always been the go to for console gpu's.  Consoles is all about power on a budget.

### REPLY:
Xbox 360 was designed by ATI but Microsoft owned the IP.  It was manufactured by TSMC. 
  
 PS3 GPU was an Nvidia chip. 
  
 AMD did make the Wii GPU, though. 
  
 CPUs were IBM, Toshiba/Sony, and IBM respectively. 
  
 Roles were reversed this gen.  Switch is an Nvidia chip, and Sony and Microsoft are both running AMD. All are CPU/GPU combos.
