处理器领域一直存在着CISC(精简指令集电脑)和RISC(复杂指令集电脑)两大阵营:CISC架构的处理器霸占了PC市场,RISC则在高端服务器领域叱咤风云。本来相安无事的两大阵营,最近发生了一次大碰撞:CISC阵营的Intel和AMD几乎同时发布了64位架构以及64位处理器产品,以Alpha芯片为代表的RISC的日子显然不好过了,下面我们就来探讨一下Intel和AMD用以和RISC“暗斗”的重量级武器。
The processor field has always existed two camps: CISC (Reduced Instruction Set Computer) and RISC (Complicated Instruction Set Computer): The processors of the CISC architecture have occupied the PC market, and the RISC has been in the high-end server field. There was a big collision between the two camps that had never happened before. Intel and AMD of the CISC camp released 64-bit architecture and 64-bit processor products at the same time. The days of RISC represented by the Alpha chip are obviously not good enough. Let’s take a look at the heavy weapons used by Intel and AMD to fight against RISC.
