NVIDIA GeForce GT 445M

NVIDIA GeForce GT 445M

NVIDIA GeForce GT 445M是一个快速的在2010年推出的中档笔记本电脑的图形卡。它是基于GF106核心,这是关系到Fermi架构。因此,支持DirectX 11和OpenGL 4.0。相反的GTX 460M,该卡只能提供144的192个着色器核心。根据不同的配置,GPU可在128位DDR3或192位GDDR5 VRAM。这两个版本之间的性能差异显著不同。 GF106架构的GF106核心的GTX 445M相关的GeFore GTX 480M的GF100核心,提供了最大192个着色器和一个192位内存总线,GDDR5。 GT 445M只有144个着色器,并在一些变种,也有更小的内存总线和DDR3。除了内存控制器,基本上可以被认为是GF106一个减半GF104。因此,老GT215(例如,GeForce GTS 350M的)或GT216(例如,GeForce GT 330M独立)内核的架构是没有可比性的。不同的是GF100,GF104,GF106和GF108核心不仅缩短了,但也有相当大的修改。相反,GF100,其目的是为专业应用,这些后者GF10x的芯片消费市场为目标。它们的特点是着色器(3X16,而不是2X16),更多的纹理单元(8而不是4)和交换网板每流式多处理器(SM)。由于尚有经调度程序(与3个着色器组),NVIDIA现在使用超标量执行,以更有效地利用量较高的着色器每个SM。换言之,着色器更有效地操作,每个核心具有更高的性能。然而,在最坏的情况下,性能也比的GF100和它的前辈的更糟糕。 ECC内存保护,这是非常重要的专业应用软件,完全被省略,缩短FP64硬件(只有1/3的着色器FP64能力,从而只有1/12的FP32的表现)。由于这些削减,大小的SM仅增长25%,尽管更高的着色器的数量和较大的经调度具有超标量调度功能。由于不同的着色器架构的着色器域和更高的时钟频率,NVIDIA的核心数不能直接相比,AMD的Radeon 5000系列(例如HD 5830)的核心。的GF104架构(也GF106和GF108的扩展)的详细信息,可以发现在桌面GTX 460条Anandtech的。因为GeForce GT 445M采用了全新的Fermi架构的性能,具有类似的核心数较老的芯片的性能是没有可比性的。一般表现很大程度上取决于所使用的内存,DDR3的性能应该是一个瓶颈。游戏性能的目的,假设同一类型的图形内存使用的Mobility Radeon HD 5850的水平上。在我们的测试中,DDR3 GeForce GT 445M的平均14%的速度比DDR3的Radeon HD 5850与DDR3。此外,基于费米的芯片提供了更高的Tessellation(曲面细分)性能比DX11的Radeon HD 5000系列的芯片。下面我们详细的基准值和游戏测试。功能一个新的特点是支持码流HD音频输出,通过HDMI蓝光播放的GF104/106/108芯片。类似的Radeon HD 5730,GT 445M Dolby True HD和DTS-HD比特流传输到高保真接收器,没有质量损失。 GT445M提供的PureVideo HD视频解码技术。视频处理器(VP4)支持的特征集C和能完全解码MPEG-1,MPEG-2,MPEG-4第2部分(MPEG-4 ASP - 例如,DivX或XviD),VC-1/WMV9,和H.264(VLD,IDCT,运动补偿,去块“)。在我们的测试中,一台1080p H.264编码的影片播放流利在非常低的CPU使用率(约1%)。 YouTube的Flash视频的1080p强调的CPU,仅在4%左右。此外,GPU能够同时解码两个1080p视频流(例如,蓝光图片,在图片)。通过CUDA,OpenCL和DirectCompute 2.1的支持下,GeForce GT 445M可以帮助一般计算。例如,数据流处理器可以编码视频大大快于现代CPU。此外,物理计算可以由GPU利用PhysX完成。某些游戏,,如黑手党2“地铁2033”,原生支持此功能。根据NVIDIA GT 445M支持3D立体幻镜也是全新的。送3D内容(3D游戏,3D网络流,3D照片,3D蓝光射线),它可以使笔记本电脑的内置3D功能的屏幕或外接3D电视的笔记本电脑制造商的支持。据传闻,应该是45瓦TDP功耗的GeForce GT 445M,包括MXM主板和内存,这是一个的Mobility Radeon HD 5830的水平。如果空闲状态时,在2D模式下,在3D模式下的节电的目的和200/400 50/100兆赫(芯片/着色器)芯片的时钟。此外,400M系列支持擎天柱从英特尔和Nvidia的GPU集成显卡之间自动切换。大多数笔记本电脑有此功能,但它的实现是完全依赖于笔记本电脑制造商。
