NVIDIA GeForce GT 640M LE

NVIDIA GeForce GT 640M LE是一个中期范围内,支持DirectX 11.1兼容的图形卡,宣布在2012年第一季度薄又轻的笔记本电脑。这是一个基于开普勒-GPU内建的GK107架构上,并在TSMC在28nm制造。显卡采用的是128位宽度的存储器接口与DDR3 VRAM。较慢的核心频率只有500 MHz的不同从一个正常的GT 640M LE模型。关注:继传闻,也将是一个基于Fermi架构的版本(96个着色器,762兆赫,DDR3/GDDR5,类似550M/555M)很可能更高的功耗比开普勒变种。开普勒架构架构是Fermi架构的继任者第一次出现在GeForce®(精视™)500M系列笔记本电脑。 GK107开普勒核心提供两种着色器块,称为SMX,每个192着色器共384着色器时钟频率以相同的速度为处理器核心的核心。虽然越来越多的着色器核心可在开普勒架构相比,Fermi设计,开普勒着色器仍有望高达两倍的电源效率。然而,由于缺少的热的着色器的域的时钟,两个着色器的开普勒芯片一样快,一个着色器的费米芯片(后者的时钟快两倍)。现在支持PCIe 3.0的移动开普勒系列和可选的Turbo模式可以自动超频Nvidia显卡的理论的15%,如果笔记本电脑的散热系统,使得它。升压模式的实施,这是在BIOS中完成的,但它最终依赖于制造商的笔记本电脑。性能由于仅有500兆赫的时钟速度,游戏性能的GeForce GT 640M LE低于640M的约20%。这是对GT 635M或GT 555M的水平相同。在重着色器的DirectX 11游戏和基准的表现是非常不错的。然而,128位内存接口,可以是一个瓶颈,如果使用DDR3绘图记忆体。像“战地3”2011年要求苛刻的游戏在1366×768和中设置播放。现在采用改进的功能集,包括支持高达4个主动的显示器。此外,高达3840x2160像素的高分辨率显示器,可以连接使用DisplayPort 1.2和HDMI 1.4a规范,如果有的话。 ,如Dolby TrueHD和DTS-HD,HD音频编解码器,可以通过比特流模式下,通过HDMI端口传输。然而,由于大多数笔记本电脑将采用擎天柱,集成的图形处理器(GPU)将有可能在显示器端口直接控制,可能会限制该功能由Nvidia的开普勒卡的设置。第5代PureVideo HD视频处理器(VP5)也集成在GK107核心,并提供高清视频的硬件解码。常见的编解码器,如MPEG-1/2,MPEG-4 ASP,H.264和VC1/WMV9完全支持4K分辨率,而VC1和MPEG-4支持高达1080p。两个数据流可以并行解码的功能,如图片,在图片。另一个新的特点是包含一个专用的视频编码引擎,类似英特尔QuickSync的NVENC API可以访问。功耗的GeForce GT 640M LE类似的旧GeForce GT 520M独立。其结果是,Nvidia的GPU是适用于薄又轻的笔记本电脑。
