    Debut of NEC's 3D Graphics Accelerator Technology a Success at SIGGRAPH 2001
    Business Wire, August 29, 2001

    Business/Technology Editors

    BOXBOROUGH, Mass.--(BUSINESS WIRE)--Aug. 29, 2001

    Fifth Generation of the NEC TE Graphics Accelerator Series is the

    Fastest Ever Produced by the Company

    The fastest graphics accelerator technology ever made by NEC was the showcase of the company's technology demonstration at SIGGRAPH 2001 last week in Los Angeles. The technology preview demonstrations, which showed NEC's line of graphics accelerator boards working on high-end, 32-bit systems using CAD, digital content creation, and broadcast postproduction applications, were a precursor to anticipated shipment of NEC's TE 5 graphics accelerator line in the fourth quarter of 2001.

    "This was a look into the future of high-end graphics design technology," said Les Silvern, Business Development Manager for Workstation Graphics. "The demonstrations definitely made people think about their creative design possibilities in 2002."

    A highlight among the technology demonstrations was NEC's TE 5 HD (High Definition) board, which, when available, will be aimed at the post-production market in preparation for HDTV broadcast. The TE 5 HD and a companion board demonstrated the functionality necessary to synchronize and edit various data streams and create a single output set. The task was performed with one workstation rather than a variety of independent hardware units.

    Graphics Accelerator Technology Summary

    The NEC TE graphics accelerator series utilizes a unique architecture that implements onboard local memory to store OpenGL display lists and instructions. This technique avoids bus bottlenecks within the workstation and makes display processing independent of other I/O traffic.

    Recent Viewperf CDRS-03 tests indicate a projected performance of 65+, which exceeds the closest competitive products. Conservative preliminary estimates of other Viewperf 6.1.2 benchmark scores will be published after I/O driver tuning has been accomplished.

    NEC TE 5 technology highlights:

    -- Two custom-designed ASICs with 0.18u technology.

    1. GRAPE LSI geometry engine -

    a highly-tuned 33M vertex/s geometry engine with local memory for accelerating vertex data access.
    Vertex Pipelines负责前期的建模渲染,处理编程的程序,NV43只是具备3个VS单元,数量不足,在渲染高分辨率的时候直接后果就是前期处理能力不足,导致数据量不足下一级的Pixel Pipelines引擎填充。

    2. PEAR LSI rendering engine -

    4组像素管线pixel pipelines

    and a wide DDR SDRAM interface for unified video memory.

    -- Up to 512MB local memory.

    -- Up to 256 MB unified video memory for texture and frame buffer.

    -- Full-scene anti-aliasing.

    显存容量是关乎到像素着色器(Pixel Pipelines)的处理,主要在纹理贴图中起重要的作用,但是显存容量并不是越多越好的
    The TE 5B and HD are expected to be announced in the US and Europe this fall and to appear in workstations from industry-leading vendors early next year.

    游客 2008-5-26 22:50:05 斯坦福大学研究生院的几个图形学方面的天才都去了nVidia
    后来OpenGL之父的加盟更是奠定了nVidia一统天下的基础
    INTEL买下了核心人员基本走光的3Dlabs,到目前还是无所作为
    另外,和3Dlabs一起过世的还有NEC的图形部门
    NEC-TE5是日 本纯国产的GPU

    TE6则是3Dlabs Wildcat Realizm 800双卡的OEM
    http://www.itmedia.co.jp/news/articles/0505/25/news030.html
    但销售情况都不好,抵挡不住6800Ultra核心的Quadro和X850核心的FireGL的强大攻势
    2006年3Dlabs倒闭后,NEC的图形部门也关闭了

    谈谈用过的几块显卡

    NEC 的TE5L:向来设计显示芯片的厂商都是欧美的居多,NEC算是比较特殊的一个。资历较老的DIYer应该都还记得PowerVR PCX2,这个是NEC推出的基于第二代PowerVR架构的显卡(仅仅是一块子卡而已),很多人搞不清楚NEC与PowerVR的关系,根据一些资料, PowerVR显示芯片的显示技术其实是来源于一家叫做Imagination的厂家,PowerVR只是获得了其授权而生产显示芯片,而最早由一家叫做 VideoLogic的厂家负责生产基于PowerVR芯片的显卡,关系够复杂吧。在这其中,NEC也有参与过相关的工作,但是具体是显示芯片的研发还是仅仅代工生产就不知道了。由于NEC的名气比较大,所以很多人只是记住了PowerVR与NEC,却很少有人提起Imagination。当然,NEC有自己的显示芯片,这就是应用于专业领域的TE系列。我最早是在MC 2000年第5期有关图形工作站的介绍中知道有这么一个东西的,当时的主要产品是TE4E,据说这块卡的性能和Quadro2 Pro差不多。7年后,终于有机会一睹NEC显卡的风采。这卡做工算是最严谨的一款了,整块卡做工很精致,分量也很重,同样是256bit显存位宽,一块光栅处理器与一块几何处理器,但是在NEC的网站上只是介绍了几何处理器的大致性能--大概在21Gflops左右。关于TE系列专业显卡,可以找到的资料很少,从我个人的使用情况来看,估计这是一块针对性很强的专业显卡,这一点从TE系列从来没有零售过可以看出来,仅仅搭配在NEC自己的高档工作站中(当年这块卡的价格可是比Quadro4 700高得多得多啊--21W日元)。具体针对什么软件我不知道,不过这也是我接触过的完全不支持DX的显卡了,驱动也小的可怜--区区700多KB。控制面板也及其简单,居然没有专业软件的选项可以选择。实际用下来嘛,性能和FireGL2相当,尤其是几何加速性能很好--主要是反映在框线与光源加速 上,尤其是光源性能;在我的平台上,是第一块在Light项突破10分的显卡!!不过在Sketchup里面的表现还是不及GVX1 Pro,但是也很不错。其余专业应用还可以,没有驱动的兼容性问题。但是最大的不足就是不支持DX,视频回放性能非常差,经常出现回放画面撕裂的问题;用 KMP的“绘制到OpenGL纹理层”稍微好转一些,但是垂直同步的问题还没有解决。这卡外表看是一块AGP4X的卡,不过在我的机器上只能运行在2X 下,但是还好没有什么其余的硬件兼容性问题。总而言之,这真的是一块工作用卡了。电脑秀-IT社区-电脑秀网站国内专业的IT产品及技术论坛 产品讨论 技术探索 术语解释 投诉求帮助)n-@1t'Y.e.R

    够详细!还是第一次了解到NEC这个双核卡的来历!

    实物的做工的确很牛!
