The point is that why talk about it's amazing power when your best example are games that were made 10 years ago. Games that already exist on PC, on nearly every OS available on PC including Linux? To play first person shooter games on a gamepad. There's a reason why the Nvidia Shield is best known for playing emulators, cause that's the best library of games you'll get on that device. Android doesn't have a library of games worth to dump $200+ on a device that can't even make phone calls. My three year old phone could do what these Nvidia devices can do, given that HL2 and Portal weren't restricted to Nvidia hardware.
Do I need to do it? Fine I will. Nvidia, baby, you need to make an x86 CPU to be taken serious for gaming. ARM will never get a library of games that will show off your graphics. Don't care what it takes to get x86 support. Get sued by Intel or whatever. They need x86.
