NVIDIA GeForce 940MX

英伟达GeForce 940MX是一款支持DirectX 12(FL 11_0)的中端笔记本电脑显卡。它在2016年第一季度已经发布,是GeForce 940M的更新。相比前代型号,它也是基于同一芯片,但支持更快的GDDR5显存。因此,它类似于微软Surface Book中的麦克斯韦尔显卡,同时搭配更大容量显存和更高频率。然而,大多数笔记本电脑厂商将采用940MX较慢的DDR3版本。

940MX的GDDR5版本似乎有还采用GM107-B芯片,搭配512个着色器而不是384个,但运行于较低的时钟频率的型号。Acer Aspire E5-774G采用的940MX提供了512个着色器(GM107),主频为795  -  861 MHz。然而戴尔Inspiron 17 7778的版本提供了384个着色器,基于GM108芯片,主频在1098至1883MHz之间。

它的性能在很大程度上取决于所使用的显存和芯片。根据我们的基准测试结果(见本页面下方),DDR3版本的性能和之前的940M非常相似(由于只有略微的提高的时钟速率)。然而,GDDR5版本的性能提高了20%(甚至30%,如果搭配快速的桌面四核处理器,不过我们缺少940M在相应配置下的分数)。因此,2015年的高要求游戏应该可以在低设置和WXGA分辨率下运行。

这款显卡的TDP在15至30瓦之间(根据版本,频率和显存不同而不同)。因此,它最适合于13英寸或更大的笔记本电脑。
