针对Intel 45nm处理器正式支持SSE4指令集,SSE4A指令集是针对2007年同期英特尔45nm新处 ...
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:]
