摘　　要：阐述了龙芯3号CPU的性能特点及应用情况,在对比了采用龙芯CPU以及Intel和AMD CPU服务器测得的实际功耗值的基础上,分析了这三种CPU在不同情况下的能耗特点以及制造工艺对性能和功耗的影响。对影响CPU功耗的主频、CPU负荷以及节能功能等因素进行了研究,提出增加动态调频和提升制造工艺的建议。This article mainly expounds the performance characteristics of the Loongson 3 CPU and its application. The power consumption feature of different CPU and CPU manufacturing technology would be take into account to figure out what may influence CPU performance and power consumption would been analysized by comparing the actual power consumption of Loongson servers measured based on Intel and AMD CPU, then make a discussion about CPU frequency, CPU load value, energy saving function and other factors that could affect power consumption. At last, we give some advices for Loongson to improve performance and reduce power consumption
