现在市场上对于同样显示芯片的显示卡往往同时有两个版本,一个是PCI版,另一个是AGP版本,对于要买显卡的人来说,往往在对买AGP还是PCI的显卡犹豫不决（不是价格因素,两者价格几乎一样）。商家往往是有什么版本,就说什么版本好,动员消费者买,而不是客观地介绍各自优缺点,究竟孰是孰非,笔者想通过本文客观地从技术上分析一下AGP的特点,澄清一些错误的认识,说明应该怎样在不同情况下购买适合自己的显示卡。 一、AGP和PCI的一些基本概念 AGP（Accelerated Graphics Port）是Intel公司开发的新一代图形总线标准。它是建立在PCI基础上的,专门针对3D图形处理而开发的高性能图形总线。它与PentiumⅡ的出现,无疑将对现行的图形工作站提出严峻考验。 1.AGP与PCI的关系
Now on the market for the same display chip graphics cards often have two versions at the same time, one is the PCI version and the other is the AGP version, for those who want to buy a video card, often buy AGP or PCI video card is hesitant (not Price factor, the price of both is almost the same). Business is often what version, what version to say, to mobilize consumers to buy, rather than objectively introduce their strengths and weaknesses, what is right or wrong, I would like to objectively from the technical analysis of the characteristics of AGP to clarify some Wrong understanding of how to buy under different circumstances for their own graphics card. First, some basic concepts of AGP and PCI AGP (Accelerated Graphics Port) is a new generation of graphics bus standard developed by Intel Corporation. It is based on the PCI, high-performance graphics bus designed specifically for 3D graphics processing. With the advent of Pentium II, it will undoubtedly put a severe test on the current graphics workstations. 1.AGP and PCI relationship
