The i7 4700MQ is comparable to an i7 3740QM, and is 10% stronger than an i7 3630QM. As for IGP : the HD4600 is about 30% stronger than the HD4000 in the same conditions.
As far as a desktop comparison the 4700mq is comparable to the 4770 set to release later this year. For graphics get the the 4700, if you aren't a gamer I would stick with the 3630.
I am going to be using it for gaming, but how much better would the performance be of the i7 4700MQ vs the i7 3630QM, if the specs are exactly the same?
