东芝Qosmio X70 笔记本电脑简短评测
性能断档。/b> 东芝的多媒体笔记本Qosmio X70上市价为1300欧元（约8581人民币）。它可以为你带来出色的处理性能，不过显卡的游戏性能略显不足，而如果能够配备固态硬盘的话系统的表现应该还可以更加优秀。
Intel Core i7-4710HQ, AMD Radeon R9 M265X, 17.3", 2.9 kgAMD Radeon R9 M265X
AMD Radeon R9 M265X是一款基于GCN(Graphics Core Next)架构的中高端移动显卡。它最早发布于2014年春，支持DirectX 12。它采用的“Cape Verde”显卡核心采用了640个统一着色器，核心频率为625MHz（通过加速最大可达900MHz）和128位的显存界面，支持2或4GB运行于1125MHz的显存。
架构
“Cape Verde”核心基于Graphics Core Next (GCN)架构，采用28纳米支撑制造。GCN架构显卡采用10个处理单元，总共有640个流处理器。另外，AMD Radeon R9 M265X采用了40个纹理单元，64个Z/Stencil ROP单元，16个色彩ROP单元和512KB的L2读取/写入缓存。
根据笔记本电脑的温度情况，它625MHz的核心频率通过AMD的Boost技术最大可以提高到900MHz。AMD Radeon R9 M265X支持最新的PCIe 3.0标准。
性能
根据核心频率和加速效果的不同，AMD Radeon M265X在2014年中属于中高端移动显卡。它的性能与GeForce GTX 850M (DDR3)基本持平。因此，这款AMD显卡可以在最高900p分辨率和中高设定下流畅运行最新游戏。但在要求较高的游戏如Crysis 3或Far Cry 3中，图形设定需要降低。
特性
AMD Radeon R9 M265X支持一些著名的功能如Eyefinity，允许用户连接最多6个显示器。对于笔记本来说，这经常由可用的显示接口所限制。
这款中端显卡同样支持Enduro技术，以提高能效，它与Nvidia的Optimus技术相似。在待机或低负载情况下（办公软件，上网浏览等），系统会自动关闭独立显卡，采用更低能耗的集成显卡。
M265X同样支持为游戏玩家设计的Mantle API。这个由生产商开发的程序界面可以作为Direct3D或OpenGL的替代。一些支持Mantle的游戏包括Battlefield 4， Thief，和The Sims 4，以及更多未来上市的游戏。
Radeon R9 M265X同样支持AMD的App acceleration技术，它可以帮助改进视频播放的质量和提高应用程序性能。不过，它要求对于OpenCL, DirectCompute或DirectX video acceleration (DXVA)的支持。
功耗
AMD Radeon R9 M265X的热设计功率为35到40W，介于840M(约30W)和 GTX 850M (约40到 45W)之间。因此，这款显卡最适合15寸笔记本使用。在低负载情况下，自动降频功能可以帮助节省能源。在待机情况下，Enduro功能可以完全关闭显卡，以节省更多能源。
