AGP是英语Accelerated Graphics Port(加速图形端口)的意思。通过字面上的意思大家应该很容易理解,这就是一个图形的端口,用于主机与显卡连接,是为了提高视频带宽而设计的一种接口规范。 早期的显卡通过ISA总线与主板连接,而随后出现的PCI显卡则是通过PCI总线与主板连接。但它们均有各自的致命缺点。首先是PCI总线最高传输速率仅为133MB/s,无法满足处理3D图形对数据传输率的要求。二是采用这种接口所有的运算将全部在显存中进行,这就需要大量的显
AGP is the English Accelerated Graphics Port (accelerated graphics port) means. It should be easy to understand, literally, that this is a graphical port for the host to connect to the video card, an interface specification designed to increase video bandwidth. Early graphics card through the ISA bus connection with the motherboard, and then appeared PCI graphics card is connected with the motherboard through the PCI bus. But they all have their own fatal flaws. The first is the maximum PCI bus transfer rate of only 133MB / s, can not meet the processing of 3D graphics on the data transfer rate requirements. Second, using this interface all the operations will be carried out in memory, which requires a lot of significant
