惠普 Envy 15-w000ng x360 笔记本电脑简短评测
Intel Core i5-5200U | NVIDIA GeForce 930M | 15.60" | 2.3 kg
NVIDIA GeForce 930M(有时也称作Nvidia Ge|Force GT 930M)是一款中低端,支持DirectX 11的笔记本电脑显卡,最早发布于2015年3月。它基于去年的GeForce 840M。除了“标准”的25瓦930M,它还有一个热设计功率12瓦的低功耗版本,支持DDR3和GDDR5显存。它的DDR3显存版本应该会比25瓦版本慢约10%。采用GDDR5的版本的性能表现尚不清楚。它的低功耗版本时钟频率仅457MHz并支持加速,它可能提供了更多的着色器(或者更大的加速空间)。
架构
相对于Kepler架构,Maxwell架构提供了一些细节优化改进,提供了更高的功效。一个更小的只使用了128个ALU算数逻辑单元(Kepler为192个)的流处理器(SMM)和一个优化了的调度器应该可以提高着色器的使用效率。Nvidia称Maxwell的128个算数逻辑单元流处理器可以提供Kepler的192算数逻辑单元SMX的90%性能。930M应该是使用了一颗3个SMM完全开启的GM108芯片(384个着色器核心,24个TMU,和8个ROP,64bit位宽)。
另外一个优化是大幅提高的二级缓存容量。更大的缓存容量可以提供对显存数据的更好管理,从而并不会因显存带宽相对较窄而性能明显降低。
与GM107核心相似,GM108核心支持DirectX 11.2。
性能
它的性能应该略低于GeForce 840M的平均表现,主要由于降低的时钟频率。这意味着要求较高的游戏如Evolve仅可在最低设置下运行。要求较低的游戏如F1 2014或Fifa 15等应该可以在最高设定下运行。请参考下面的游戏运行测试成绩了解更多细节。
特性
GM108核心集成了第六代的PureVideo HD视频引擎(VP6),提供了对H.264和MPEG-2视频的更好解码性能。当然,VP6支持所有前代的功能(4K支持,PIP,VCENC API视频编码)。遗憾的是,它仍未提供对HDMI 2.0的支持。
功耗
GeForce 930M的功耗应该会低于33瓦。因此930M适合于13寸或更大的笔记本电脑使用。900M系列同样支持Optimus技术,可以自动在集成显卡和Nvidia独立显卡间切换。
