AMD currently supports only 4 instructions from the SSE4 instruction set, but have also added four new SSE instructions, naming the group SSE4a. These instructions are not found in Intel's processors supporting SSE4.1 and alternatively AMD processors aren't supporting Intel's SSE4.1. Support was added for SSE4a for unaligned SSE load-operation instructions (which formerly required 16-byte alignment).{shocked:] 作者: 斯大林 时间: 2011-6-9 17:30
SSE4.1对日常应用意义不大,缺少这个指令集一样用得欢,如果要视频渲染这些用得多,到很有必要,当年研究E7500和E5300取舍的时候就已经看了很多介绍,大致记得是这样,呵呵!
