The Core i chips belong to Intel’s Sandy Bridge family of latest central processing units (CPUs) for computers. The CPU serves as the brain of the computer which determines how fast the computer will run applications.

The Sandy Bridge chips for mobile computers (netbook or notebook) are designed to use less heat and energy than earlier processors.
In general, Core i7 is better than Core i5. Of course, Core i5 is better than Core i3.
Compared to the previous Pentium and Celeron processors, all of the Core i family are better for heavy multimedia applications but Core i7 essentially have more capabilities than Core i5 and Core i3.
The entry level of the Core i family, Core i3 can get the job done for most applications. Core i3 usually have 2 cores and 4 threads with 3-4 MB Cache, but there are also 4-core models for Core i3.
Core i5 is the mid-size processor with a little more capability compared to Core i3. Core i5 also has 2-4 cores and 4 threads but with higher clock speed than the Core i3 and higher 3-8 MB Cache.
At the helm of the family is Core i7 designed for the most intensive applications on the planet. Usually with 4 cores and 8 threads running on 4-8 MB Cache, Core i7 is the fastest Sandy Bridge processor geared to provide more energy efficiency.
