While it did seem like a GeForce Experience counterpart at first, there were a couple of important differences. Gaming Evolved relied on crowdsourced data and was based on a customized version of Raptr, so AMD's involvement with the tool was quite limited.
Gaming Evolved used to be bundled with AMD's Radeon Software drivers but WCCF Tech noticed this is no longer the case so the site decided to reach out to AMD to discover what's going on. Turns out Gaming Evolved got dumped, but AMD isn't sharing why:
Starting September 12th 2016, AMD is no longer bundling the “AMD Gaming Evolved App” by Raptr with builds of Radeon Software. The application will still work. AMD will cease to undertake any compatibility testing, install support or general technical support for this application, nor will it be available through Radeon Software or its installer. Previous builds of Radeon Software that include the “AMD Gaming Evolved App” dated before September 12th 2016 will remain intact and will not be affected. -AMD
