Well technically speaking the Hardware will get identified correctly through the Acer Custom Drivers, but when you use AMD official Drivers they identify the hardware as you saw an R7 version. So 1st thing is to ask your Laptop Manufacturer (Acer) to provide updated drivers first. Then comes the bad news from AMD, APU Builds like yours are only Updated on the WHQL version so check the downloads page and see if your APU is still supported or had its support temporarily removed until the next WHQL release (You do this by going to latest driver on Manual downloads and look at its release notes). If it lists your APU as one of the ones not supported, then you are Limited 15.12 WHQL driver or 16.2.1 Hotfix or Legacy driver!
At least until AMD releases the next WHQL Driver, but with all their woes with Hotfix drivers on their new RX480 cards who knows when that would be, it was supposed to be out at end of June but so far none has been released yet!
