what is the difference between intel CPU i3,i5 and i7

I3,i5,i7 difference as follows I3 is dual core four thread,3 MB level 3 cache Four core i5 is four thread,6 MB level 3 cache Four core i7 is eight thread,8 MB level 3 cache And the main frequency,i3 2100 and i5 2400 basically flat,i7 2600 higher frequency Of course i5 also have common version of 2300 and not overclocking lock times frequency version of the 2500 K ,I7 2600 K I3 is not ruling accelerating technology of frequency,and i5 and i7 is the frequency of the technology problems Ruling by reducing the frequency is the core of the frequency to improve the frequency of the core To improve performance,and no more than rated power technology i3,i5,i7的差别如下i3是双核心四线程,3MB三级缓存i5是四核心四线程,6MB三级缓存i7是四核心八线程,8MB三级缓存并且主频方面,i3 2100和i5 2400基本上持平,i7 2600主频较高当然i5也有普通版的2300和超频不锁倍频版的2500Ki7也有2600Ki3是没有睿频加速技术的,而i5和i7都是由睿频技术的睿频就是通过降低部分核心的频率来提高部分核心的频率使性能有所提高,而又不超过额定功率的技术
