1 AGP 前面已经讲过AGP接口是专用的加速图形端口,和PCI接口相比具有很大的优势。其实AGP比PCI的最大优势在于其DIME工作方式。现在的3D显卡所要处理的数据是相当巨大的,对显存容量的要求也很高。显存的容量直接制约着纹理的精度,进而直接影响到3D图形的精细程度,但高分辨率的大纹理贴图却受到硬件条件的限制:电脑在处理纹理数据时,要预先将贴图读入纹理缓存,因此显存容量 1 AGP As already mentioned AGP interface is a dedicated accelerated graphics port, and PCI interface has a great advantage. In fact, the biggest advantage of AGP over PCI is its DIME mode of operation. Now the 3D graphics card to deal with the data is quite huge, the memory capacity requirements are also high. The capacity of the video memory directly restricts the accuracy of the texture, which directly affects the fineness of the 3D graphics. However, the high-resolution large texture map is limited by the hardware conditions: When the computer processes the texture data, the texture is pre-loaded into the texture cache , So memory capacity
