This is a very interesting but also frustrating comment. If you're right that it's not a console grade renderer (not that I know what that even means) then that's really interesting - but why not? And could it be in future or is it fundamentally impossible for some reason?
Maybe they mean like the golden era of Xbox 360 rendering. Where the CPU and GPU could run together in one region of unified 512MB of memory with crazy fast rendering bandwidth. I wish there was a VR headset designed like that.
