nVIDIA的SLI和ATiCrossfire的出现,我们可以成双成对的添置显卡,让图形性能更强劲,让更新速度更缓慢,这就是双(多)卡互连的好处。多块显卡同时在一套系统上使用还给我们提供了更有趣的使用方式—多头输出,尽管我们还在期待nVIDIA打开SLI多卡互连的限制(实际上这很容易做到,就像电源的开/关那样容易,因为SLI技术在驱动中就可以做变更),尽管我们的系统需要更大的电源以支撑这看似“庞大”的电力消耗,但是,我们得到了只有专业级显卡才能得到的功能,价格也只是专业级显卡的几分之一。举例来说,平时我们看到的屏幕墙,如金融领域的证券交易所,或是形象展示电视墙等等,背后都是由一套采用多块专业多头输出的显卡来实现。一提及专业应用,价格自然也相当“专业”,动折万元的投入不是笔小开销!典型的例子便是NVIDIAQuadroNVS400,nVIDIAQuadroNVS400能支持四组显示输出,这样一块专业显卡的价格在四千元左右,如果打造一个八显示器的电视墙,那么你至少要在显卡上投入八千元之多,加上电脑主机其他配件的价格,必然超过一万元!而像技嘉GA-8N-SLI-QUADRoyal主板与技嘉Geforce6600GTSilent-PipeII显卡的组合,不仅可以在游戏应用中实现四显卡SLI,而且在专业应用上,也完全可以取代专业级的电视墙系统。这一套的价格仅为六千元上下,相比专业级系统要便宜了近40%。
With the advent of nVIDIA’s SLI and ATiCrossfire, we can add graphics in pairs to make graphics more robust and slower to update, which is the benefit of dual (multiple) card interconnects. Having multiple graphics cards on one system at the same time gives us a more interesting way to use them - long output, although we are still looking for nVIDIA’s ability to turn on SLI multi-card interconnect (which is actually pretty easy to do, just like power On / Off as easy as SLI technology can be changed on the fly), although our system requires more power to support this seemingly “huge” power consumption, we have only professional graphics Get the function, the price is only a fraction of the professional graphics card. For example, we usually see the screen wall, such as the financial sector stock exchange, or the image display TV wall, etc., are behind by a set of professional multi-output graphics card to achieve. A reference to professional applications, the price is naturally quite “professional”, moving a million investment is not a small overhead pen! A typical example is NVIDIAQuadroNVS400, nVIDIAQuadroNVS400 can support four sets of display output, so a professional graphics card price of four thousand dollars If you create a eight-monitor TV wall, then you at least put a card as much as eight thousand dollars, plus the price of the computer host other accessories, must exceed 10,000 yuan! And like Gigabyte GA-8N-SLI-QUADRoyal The combination of motherboard and Gigabyte Geforce6600GTSilent-PipeII graphics card, not only in the game application to achieve four graphics SLI, but also in professional applications, but also can completely replace the professional-level video wall system. The price of this set is only about 6000 yuan, nearly 40% cheaper than the professional-grade system.
