Most i7 mobile CPU are quad core with Hyperthreading (4 cores 8 threads) , some M CPU are dual core like i5
All i5 CPU are dual core with HT ( 2 cores 4 threads)
Quad Core > Dual Core
i5 , i7 have turbo boost . i3 is the same as i5 but it has lower clock speed and no turbo boost
Haswell is code name of 4th gen Core I series i7 4xxxMQ which the latest CPU atm , Haswell is much faster than last gen Ivy Bridge i7 3xxxQM
There is only 1 reason why I didn't get the i7 at that time (2-3 years ago)
i7 clock speed was too low
There was only 2 options for me at that time : either i7 720QM or i5 480M .I'm sorry but i7 720QM @ 1.6GHz is so pathetic compared to i5 480 @ 2.6GHz . With Turbo Boost , it only bump up to 2.4GHz with 2 cores active while i5 can bump up to 2.9GHz with 2 cores active

I'm glad that Intel has improved the clock speed recently . So I could buy i7 next time (2015)
Btw , There is i7 4702MQ benchmark result on Dolphin Benchmark
i7 4702MQ is slower than i7 4700MQ but it chops off i7 3630QM completely

Quote:you have a i5 480m, and i suppose it's efficient, but why not a i7 ?Nehalem is code name of 1st gen Core series (i5 4xxM/5xxM ; i7 6xxM/ 7xxQM / 8xxQM / 9xxXM)
