Difference between 2nd and 3rd generation i3 i5 & i7 Processors
Each generation of intel processors has codenames starting with Westmere (First Gen) upto Skylake (6th Gen)… Every year Intel improves upon the process and the architecture of their processors.
Second Generation (Sandy Bridge) Intel Core i3, i5 & i7 laptop processors.
2nd Generation of Core i3, i5 & i7 processors is called SandyBridge Processors. These are up to 15% faster than the previous generation at the same clock speeds. They consume less power and the battery backup is more. 2nd Generation processors were introduced in 2011 .The 2nd gen is 32nm. 2nd generation processors include new features for improving the Graphics performance of the processors such as Intel InTru 3D / Clear Video HD and WiDi 2.0 that were not available in 1st generation processors.
Third Generation (Ivy Bridge) Intel Core i3, i5 & i7 laptop processors.
3rd Generation of Core i3, i5 & i7 processors is called Ivy Bridge. It was introduced in late 2012 at the moment it is the latest and the fastestGeneration, Third gen is about 5%-8% faster than second Generation Sandy Bridge Processors & up to 45% faster then the 1st Gen.
