AMD Radeon HD 7500G + HD 7550M Dual Graphics
AMD的Radeon HD7500G+ HD7550M双显卡是一个集成了AMD Radeon HD7500G APU处理器的图形卡和一个专用的入门级的AMD Radeon HD7550M显卡交火组合的结合。这就是所谓的AMD双图形或不对称的交火，并使用AFR（交替帧渲染），呈现不同的帧上的两个图形核心。因此，组合也有从微观口吃（两幅图像之间不同的空间导致口吃，虽然足够高的帧率流畅的游戏只有一个GPU）。双显卡解决方案的性能在很大程度上取决于驱动程序支持的游戏。在一些游戏中的表现，甚至可能降低10％-15％，相比只使用APU的图形卡。在我们的测试中，将CrossFire组合是最好的5-10％左右的速度比单7550M。因此，由于微口吃和性能问题，双显卡可以征收更多的问题比带来的性能提升。只有在最好的情况类似的GeForce GT 630M的性能是可能的。两片显卡的PureVideo HD（UVD3）或OpenCL支持的功能，如类似。由于两个显卡渲染帧时，功耗是明显高于使用只有一个GPU。
