Exactly Lambchop
Really, it lists it's sources, one of which is a completely not official and definitely not real roadmap that turned up, iirc, like a year ago and was widely posted around the usual tech sites. The other source is that stupid GP100 gddr5/hbm2 link again on the usual tech sites what, a week ago or so.
I honestly don't have the effort to go back and look but I'm like 99% sure you commented on the recent story and I'd be surprised if you haven't commented on or linked a story based on that roadmap previously.
What part of it is new, look at the sources, look at the rumour. It's identical rumour with nothing new posting existing sources(one extremely old) which clearly aren't accurate.
You'll post this same information again in two weeks when another woeful site runs the same story written in slightly different words with slightly different sources which themselves will link to the same sources as now.
