两代旗舰同频PK：Core i7-3960X对i7-990X

功耗测试

功耗测试部分采用的平台与之前相同，Core i7-3960X的核心电压为1.18V，Core i7-990X的核心电压为1.2V，频率仍旧为4GHz，采用带读数的电源插座测整机功耗做对比。测试方法为同时跑12个SP2004使CPU满载，另外再测量空闲时CPU的功耗。

笔者本人看到功耗测试结果对比时也大吃一惊，同为32nm工艺制程，新的Core i7-3960X在电压只低0.02V的情况下功耗居然比上代旗舰降低80-100W，不知是测试平台的BUG还是Intel在代码方面变了什么魔法。

总结

在性能超出一定幅度的情况下，Core i7-3960X对比上代Core i7-990X功耗有大幅度的降低，并且定价很可能仍然在1000美元左右，这样看来对于发烧友级别完全不在乎价格的玩家来说，LGA 1366平台到时候是可以马上换掉了。
