1st Generation of Core i3, i5 & i7 processors is called Nehalem Processors. They are less fast then the Second and Third Generations. We also find that this generation is obsolete now. They consume more power because of which the Battery backup is less. 1st Generation processors were introduced in 2010. Nehalem processors are 45nm from that we understand; they’re up to15% slower than the next generation at the same clock speeds.
- First generation (Nehalem Processors) Intel Core i3, i5 & i7 laptop processors.
- Third Generation (Ivy Bridge) Intel Core i3, i5 & i7 laptop processors.
