IF this is a Desktop GPU Card there is only one HD7600 series GPU card listed as HD7670. It is a Non-Support GPU Card with no more AMD Driver updates: https://www.amd.com/en/support/graphics/amd-radeon-hd/amd-radeon-hd-7000-series/amd-radeon-hd-7670
You have a choice of two AMD Drivers to install:
1-WQHL - 2015
2-BETA - 2016
IF this is a laptop then you need to post the exact Make & Model of your Laptop and APU and GPU installed.
There are several laptop HD7600M Series AMD Drivers: https://www.amd.com/en/support
But if your Laptop has an AMD APU (Processor with Integrated Graphics) with a HD76xxM GPU card then you MUST install the APU driver which will install automatically both the Integrated and HD76xxM Graphic Drivers in your Laptop.
