联想 ThinkPad P51s (酷睿 i7, 4k) 工作站简短评测
Intel Core i7-7600U | NVIDIA Quadro M520 | 15.60" | 2.2 kg
英伟达Quadro M520是一款面向移动工作站的显卡,兼容DirectX 12(FL 11_0)和OpenGL 4.5。是一个基于Maxwell的显卡,采用带有384个着色器核心的GM108芯片,由台积电(TSMC)在28纳米级别制造。这意味着它与Quadro M500M(DDR3)类似,但配备了更快的GDDR5内存。 带有GDDR5内存的GeForce 940MX是Quadro M520的消费级别产品。
Quadro系列提供经过认证的驱动程序,针对CAD或DCC等专业应用程序的稳定性和性能进行了优化。例如,OpenGL的性能应该明显好于类似规格的GeForce显卡。
构架
与Kepler相比,Maxwell已经在几个细节上进行了优化,以提高能源效率。只有128个ALU(Kepler:192)的较小流式多处理器(SMM)和优化的调度程序应该能够更好地利用着色器。英伟达承诺,拥有128个ALU的Maxwell SMM可以提供具有192个ALU的Kepler SMX 90%的性能。GM108具有3个SMM,因此具有384个着色器核心,24个TMU和8个ROP(64位接口)。
另一个优化的地方是:大规模放大的L2缓存。较大的容量可以减少一些内存流量,以允许相对较窄的存储器接口,而不会显着地降低性能。
GM108支持DirectX 11.2 (仅支持的11.0级别)和DirectX 12。
性能
目前,M520型号的时钟频率尚不清楚。应该与带有GDDR5的消费级别产品940 MX类似。因此,性能应该与Quadro K620M相似。
特点
功能应该包括对最多四个活动显示器的支持。使用DisplayPort 1.2或HDMI 1.4a(HDMI 2.0不支持)可以连接高达3840x2160像素的高分辨率显示器。 HD-Audio编解码器(如杜比TrueHD和DTS-HD)可以通过HDMI端口通过比特流模式传输。 但是,由于大多数笔记本电脑都具有Optimus特性,集成的GPU可能会直接控制显示器端口,并可能会限制Nvidia Kepler显卡提供的功能。
采用了CUDA或OpenCL,Quadro M520的内核可用于一般计算。
GM108集成了第六代PureVideo高清视频引擎(VP6),为H.264和MPEG-2视频提供更好的解码性能。 当然,VP6支持上一代的所有功能(支持4K、PIP、通过NVENC API进行视频编码)。
能耗
M520的功耗额定功率为25瓦TGP(包括内存和电路板在内的最大功耗)。略低于额定功率为30瓦的M500M。因此,该显卡最适合的是13-14英寸及以上的笔记本电脑。M500M还支持在集成显卡和英伟达显卡之间的自动切换。
