The most exciting thing to me in portable PCs is the 'VR backpack' form factor. As cool as the HTC Vive is, moving around with a fat cable sticking out the back of your head is a big detriment. Putting the PC in a backpack will be so perfect for VR - bigger batteries, more efficient (without the LCD), no cables.

These GPUs will make VR backpacks even more viable, with reduced power consumption, better performance and reduced size. I am super excited to see what will be coming out in this field over the coming years.
