How to know if a processor is 2nd Generation core i3, i5 or i7 ?
The 2nd Generation Intel Core i3, core i5 or the core i7 processor are easily differentiable by their part numbers. The part number of the 2nd generation for core i3, i5, i7 processor start with 2 after core i3- or i5- or i7- prefix. As an example core i3-2310M is a 2nd Generation core i3 processor while the core i3-350M is a 1st generation core i3 processor.
An easy to remember is the fact that the 2 in 2nd generation matches the start of the part number.
The 2nd Generation Intel core processor are also popularly known as the Sandy Bridge processors. There have been significant evolutionary improvement with respect to the 1s generation Arrandale processors. Here are these
– The two dies have been unified. We now have a single 32 nm die. In first generation core i3, core i5 and core i7 processors, there are two dies – the firs one with 32 nm has the two cores while the second die with 45 nm technology has the memory and graphics controller.
– There has been significant improvement in the turbo boost technology for the i5 and i7 processor. The processor can stay in the boosted frequency for a longer time.
– The most significant improvement is in the area of the integrated graphics where we can expect a x2 performance improvement.
