the 2nd generation chipset is based on 32nm architecture while the 3rd gen has a 22nm architecture...
the 3rd gen processor produces less heat, is more energy efficient and has better inbuilt graphics than than 2nd gen.

As a manufacturer, Intel has committed to switching things up every generation of its cpu chips. They alternate between an architecture change and a die shrink with each other generation.

The 2nd generation of Core i-series processors was dubbed "Sandy Bridge" and was an architecture change from the previous CPUs.

The 3rd generation is called "Ivy Bridge," and is basically a copy of Sandy Bridge manufactured on a smaller scale, or die. However, Intel also focused on beefing up the integrated graphics in this generation.

Basically, 3rd generation "Ivy Bridge" CPUs have a small (5-10%) performance advantage over 2nd generation Sandy Bridge chips, however they also produce higher temperatures when overclocked which means it is harder to push them further in speed. Basically they even out when compared to Sandy Bridge's performance+overclocking.

However, the Ivy Bridge CPUs also use less power and have a more powerful graphics chip built in.
ivy-bridge uses 22nm lithography.
Higher clock speed
powerfull built in gpu with hd 4000
overclocking potential is slighly weaker

sandy-bridge uses 32nm lithography
lower clock speed
Built in gpu with hd 3000
overclocking potential is great

Good info
