If you look close one might see that those slides are camera phone pics of a large screen presentation, there is a date of February 2015 on one.
If its fake its a fairly elaborate one, it has all the hallmarks of a member of an audience sneaking phone pics of the presentation out.
It may have been a private presentation of some kind, like an investors event, 'someone' from AMD may have invited one or two press along for the event to 'accidentally leak' some of it.
I hope it's legit. This likely max chip spec, consumer chip could see 6/8 core CPU with decent IGPU with HBM.
I would def put a system together with an APU like that and some fast DDR4, make a great all in one Mini-ITX.
