我们经常可以从各种报刊文章中看到,笔记本电脑在性能上仍旧与桌面PC存在相当大的差距:一方面是由于笔记本的处理器在主频上仍旧与桌面PC存在一定的距离,另一方面也是由于其它部件在性能上也不能与桌面PC同日而语。比如,显示卡。作为笔记本电脑部件中的一份子,笔记本电脑的显示芯片也同样需要尽量满足体积小巧、功耗低这两个大前提。因此,再桌面PC的显卡领域中大展拳脚的nVidia公司在笔记本电脑领域却收获不大——其中最重要的原因就是该公司的显卡功耗太高,发热太大。目前,在笔记本电脑中得到广泛应用的图形芯片主要 We can often see from various newspaper articles that the performance of a laptop is still quite different from that of a desktop PC. On the one hand, the notebook processor still has a certain distance from the desktop PC at the same frequency. It is also due to other components in the performance can not be the same day with the desktop PC. For example, the video card. As part of the notebook computer components, laptop graphics chips also need to try to meet the small size, low power consumption of these two major prerequisites. As a result, nVidia, which makes a big splash in the graphics area of ​​desktop PCs, has seen little gain in the notebook space - the most important reason is that the company’s graphics card consumes too much power and generates too much heat. At present, the main application of the graphics chip in notebook computers
