Pixels/second aren't a very useful metric when speaking about CPU performance. Your comparison seems to show that CPU performance might be much more important than GPU perf for VR. Also, you're correct that GPU's can play all sorts of tricks to get multiple projected views for low CPU-overhead. But that is with significant software support. Otherwise VR will have to build twice the amount of framebuffers/frame as a single view game.
