if getting the 13 inch MacBook pro, what are the advantages of configuring it with a core i7 chip. And also do Intel iris graphics have dedicated memory?
 
Apple is 2 years behind on graphics or on the high end 15". It depends

There is zero advantage of getting an i7 upgrade on the 13", because both dual-core i5s and i7s have 2 cores and 4 threads. Performance difference is almost nil.

Between a quad-core i5 and quad-core i7, the difference can be significant due to hyper threading in the i7 (which is absent in desktop i5s).

And no Mbps have quad cores?

Only 15" have quad-core i7s, with 4 cores and 8 threads (just like desktop i7s).

13" only have dual core i5s and dual core i7s. Both have 2 cores and 4 threads.

Are the 15 inch MacBook pros still portable?
 
I got a 15"rMBP + GT750m

It's perfectly portable. I used to have a 17.3 inch Asus laptop which weighed like 4+kg. I have my macbook for half a year now, and when it's in my backpack i still check if i didn't forget it, because it's so light.

Yes, it is. I enjoy how small and light-weight my 13" rMBP is compared to the 15" rMBP I used to have.

However, if you need a bigger screen and/or more power the 15" is the obvious way to go.

If not doing intensive video editing, would you notice a difference in performance?

For light tasks where multi-core performance does not matter, no.

Does watching movies, playing music, multitasking with web browsing, word processing, running GIS, modelling and CAD all count as light tasks?
 
Also which MacBook Pro is just as powerful as my current notebook, which is this one - http://www.notebookcheck.net/Review-Dell-XPS-17-Notebook-i7-2630QM-GT-555M.51949.0.html?

Yes but obviously the 13 inch is more portable.

I've used both 13" and 15" and while the 15" is a tad heavier its every bit as portable as the 13" Depending on your usage habits, the 15" is an excellent option.

The base-model 15" would have better CPU performance.

What about graphics? I'm thinking about whether I should replace this notebook completely or have a portable lower spec device and use the dell notebook for power usage on a desk.
 
I think you should just get the 15" with dedicated graphics. It is an investment. But it's definitely worth it!
