自从PC机问世以来,在很长一段时间内,显示器、CPU、内存、硬盘始终是最昂贵的硬件。随着硬件技术的不断进步和日益白热化的市场竞争,这些配件的价格始终在日益下跌,在整机价格中的比例越来越小。在过去,我们总是强调提高CPU的速度和性能,内存的带宽、容量、稳定性,减少性价比来提高计算机系统的整体性能,然而,根据Amudal定律,一个部件性能改进后,整机性能的改进依赖于改进部件在整机中所占的比例;而且,无限制的不断改进某一个部件,对整机的性能影响不大。关键是实现整机中各组成部分的协调。近年来,随着家庭电脑的多媒体化和3D游戏的快速发展,计算机应用的研究重点已逐渐从数据、文字处理转向多媒体应用,从简单的图标窗口,到复杂的图形和高质量的画面处理,原来的CPU的负担越来越大,我们只能改用其他方法来缓解CPU的压力,于是产生了显卡。随着家庭电脑的多媒体化,游戏程序的设计中经常出现大规模的三维场景,虚拟显示等因人入胜的画面。并且随着网络技术的发展,计算机要处理的数据量越来越大,要求计算机处理大规模数据的速度要大大提高,对计算机提出了严峻的要求。审视显卡技术发展的现状,展望未来的技术趋势,我们将对整个3D技术有一个更为深刻的认识。

Since the advent of PC-year, in a very long time, monitors, CPU, memory, hard disk is always the most expensive hardware. With the continuous advancement of technology, hardware and increasingly heated competition in the market, the price of these accessories has been a growing decline in prices in the whole is getting smaller and smaller proportion. In the past, we always emphasis on increasing the speed and performance of CPU, memory, bandwidth, capacity, stability, reduce the cost-effective to improve the overall performance of computer systems, however, in accordance with the law of Amudal, a part of the performance of the improved machine performance improvements to improve the parts dependent on the proportion of machine; Moreover, the unrestricted parts of a continuous improvement of machine performance impact. The key is to achieve the various components of the whole coordination. In recent years, with the family of multimedia computers and the rapid development of 3D games,
