Hold your horses! That video is quite old, or only slightly improved from the one I saw over a year ago. There is a lot of hyperbole around this engine, mainly due to the way the narrators pitch it.
I'm hugely sceptical about it.
I remember them saying the demonstration in the first video was run on a regular laptop of the time. So probably a 2-core (not 12-core) machine. I believe this is possible, as Intel were working towards the same thing as well. They went for the increased core number though.
Still, I believe it more now that they've returned with new content from being "dead" for a year, and are being funded by the government.
