I would bet it's more likely that the OEM who is using and asked for those chips demanded they be a 5000 series part so that customers weren't skipping it over because of "last gen". I completely agree it's dishonest, I'm not sure you can blame AMD though. If Dell (I'm not saying this was Dell), came to you and said: either this chip is 5000 or I don't carry ANY of your chips, you give them what they want. To me this shows AMD has learned its lesson: without the OEMs onboard you aren't going anywhere. Selling individual chips to gamers is profitable, but that only goes so far.
