This question is very good to answer, as the server's cpu Xeon is a word of stability. In the application is not necessarily stronger than the i7, the problem is that the strongest board is multi-chip, the program running on the server is mostly distributed computing. To give you an image metaphor, it is like you drive a big truck to work. Compared with a car, your big truck is more solid and stable, but your office efficiency is certainly not comparable to your car. The two are not the same thing in the same field, and they cannot be compared.
