yes and i explained the difference, for the 1080 thing, he puts a context, he doesnt have to put it in context for you, he puts a slide behind him and say what he wants it's for you to link his words to the slide, this is legal PR deceit.
but on the 1070, there was no context no slide nothing for you to link to his words to come up with a different conclusion, it was a simple and direct with no wiggle room 1070 faster than TitanX, if it's not true, nvidia is liable for false advertisment, therefor it has to be true.
It only needs to be faster in one thing for the statment to be true.
IMO it will be in VR with the new optimisations not general everyday gaming but time wil ltell
