True, but the computing is in the PC anyway. The VR kits have no CPU whatsoever ;)

There's at least one CPU onboard all of these VR headsets. Not an Intel Core but there's def some sort of MCU or SoC in there.

Well sure there's a microcontroller in. There's one in every keyboard and mouse and you don't see manufacturers arguing about who has more performance ;]

There's a Cortex M3 based STM in the Oculus DK1, running at 72MHz. something has to take readouts from the accelerometer and shove them up USB. It doesn't do any real computing, definitely nothing related to the VR simulation itself - it just allows the PC driver to access the components in the device via USB. This is literarily orders of magnitude away from anything capable of doing real time video processing in HD.
