Difference between Intel i3 and i5 processor?

Question

Intel Core i3, Core i5, and may be Core i7 CPU have been there from last 1-2 years but I don't know the real difference between these. Can someone help me with the difference between these three so that I can decide which one to buy.

Answer 1

Few points should help you -
1. Core i7 does not have seven cores, code i5 does not have have five nor does Core i3 have three cores.
2. Numbers next to i is the relative processing powers or we can say i7 is better than i5 and i5 is better than Core i3 in terms of processing power.
3. i3 is called i3 because of it is rated with three stars, i5 has four stars, and i7 has five. Celeron and Pentium have get one and two stars respectively.
4. All i3 are dual-core processors, all i5 processors are quad cores (with some exceptions) where i7 is also quad-core with hyper threading where each core can handle two thread so we can say 8 core.

Now its upto you what is your requirement and what is the cost you are ready to pay.....
