2.2GHz Pentium系统引起了巨大反响 现在,英特尔推出了2.2GHzPentium 4——看起来这只是个人电脑高速公路上的又一次速度提升。然而事实并非如此简单。英特尔将此款处理器的一级缓存从256KB增加为512KB,同时将生产工艺从0.18微米改进到了0.13微米(这款产品命名为Northwood)。在原有的2GHz处理器的基础上,性能提高了30％,本来人们以为换代产品的性能最多只能提高10％,这一事实大出人们的意料。 2.2GHz Pentium System Reacts Generously Now that Intel has introduced the 2.2GHz Pentium 4 - it looks like it’s just another speed boost on the PC highway. However, the fact is not that simple. Intel increased the L1 cache for this processor from 256KB to 512KB while improving the manufacturing process from 0.18μm to 0.13μm (this product is named Northwood). On the basis of the original 2GHz processor, the performance has been increased by 30%. People originally thought that the performance of the replacement product can only be increased by up to 10% at the most.
