AMD Radeon HD 8690M
AMD Radeon HD 8690M（有时也被称为了ATI Mobility Radeon HD 8690）是DirectX 11.1显卡的笔记本电脑。就像8500M和8700M系列，它是基于384着色器核心，24 TMUs，16个ROPs在火星上芯片（28nm制GCN架构）。核心主频为775 MHz（或增强）高达825 MHz的，并且可以访问GDDR5 VRAM（64位，1125兆赫）。的Radeon HD 8690M的性能应该是在范围内的GeForce GT 630M和Radeon HD 7670M。当前和要求苛刻的游戏，如“孤岛惊魂3流利的中低的分辨率和细节设置。 384着色器可以使用与OpenCL 1.2通用计算的（8计算单位）。老万亿次芯片相比，基于GCN-火星的体系结构提供了更好的性能，在此框架内。特色的8690M包括通过UVD3视频解码进行解码的MPEG-4 AVC/H.264，VC-1，MPEG-2，和Flash直接从AMD GPU。多视图编解码器（MVC）和MPEG-4的第2部分（DIVX，XVID）的高清视频是目前兼容。 8600M系列还支持集成的GPU和独立显卡之间的自动显卡切换。耐力赛，这项技术取代了AMD的动态切换显卡，是类似于NVIDIA的Optimus。另外，8690M可以直接支持2个连接显示器如果耐力赛被禁止使用Eyefinity技术。的8600M系列的其它特征包括ZeroCore为降低功耗，当显示器关闭和电源选通区域中未使用的芯片断电。 PowerTune允许的显卡的GPU自动超频和降频是在其TDP限制。例如，该芯片可以降频运行时的FurMark和OCCT，但会在某些游戏如“失落的星球”，“孤岛危机”，“生化危机5超频。集成的HD音频处理器能够通过HDMI和DisplayPort（例如，蓝光视频）传输高清音频（TrueHD或DTS Master音频）。此外，现在它可以同时并行多个设备的音频输出与新的离散数字多音频（DDMA）功能。的功耗范围内的旧HD 7670M。其结果，适合于13英寸的笔记本电脑或更大8690M。
