处理器，打破了一向由Intel主导x86规格的定理，以往由8Bit提升至16Bits以至32Bit都是由Intel所带动，而进入64Bit时代，AMD终于一雪前耻领先对手。</P> <P>虽然Intel一直反击对手，认为现时PC处理器并不需要64Bit运算能力，反而是需要更高的运算速度，只可惜Intel的90nm工艺未如理想，频率并没有太大上升的空间，面对AMD K8的64Bit的攻势，Intel没法不顺从大势急忙找寻对策，推出64Bit的解决方案，命名为EM64T。</P> <P>EM64T技术全名为Intel Extended Memory 64 Technology，是现时IA-32架构的加强版本，故此在决定命名为EM64T前是叫作IA-32E，只是名字上没有64字眼看上像被对手比下去，才在最后改名为EM64T。Intel率先把这技术引入于新一代Xeon伺服器级处理器及工作站级的Pentium 4处理器中，主要是为了提供更大的记忆体定址能力，突破32Bit的记忆体定址极限，此外EM64T支援64Bit的作业系统及64Bit软件运作的同时，亦能提供32Bit作业系统及32Bit软件的支援，基本是Intel的EM64T可以说是根据AMD x86-64而设计并完全兼容AMD的x86-64模式，彷佛Intel就在拷贝AMD的技术似的。 </P> <P>这次我们拿到的这款处理器是Pentium 4F 560 工作频率3.6GHz，采用Prescott核心，90nm工艺，支持Intel EM64T技术，配备1MB L2缓存，电压1.4V。目前该处理器还没有真正开始销售，预计价格和32位的Pentium 4-560（3.60GHz）持平。</P> <P align=center><IMG height=188
