i3-330m的得分是6100±100，i7-640m的得分在10000±100，i7-740QM的得分是11000±100强百分之十这样，但是超过了720QM。顺带说句一代四核i7的秘密吧。i7-740QM的单核最高睿频到2.93Ghz(22x133Mhz，22x倍频),双核最高睿频2.8Ghz(21x133Mhz,21x倍频），四核最高睿频1.86Ghz(14x133Mhz,14x...
I7 720QM的优势在于其为4个物理核心,而且L3缓存容量高达6MB,不过I7 640M的主频高达2.8GHz,比720QM的1.6GHz高很多!而且I7 640M支持睿频(3.46GHz)和4个逻辑线程,多任务能力也不算很差...综合考虑我觉得I7 640M更好,毕竟在笔记本平台上,4个物理核心用处不大,L3有4MB足够的了,最最重要的主频方面...
