What is the Difference Between 1st Generation and 2nd Generation Intel Core i5 Processors?

The main differences between 1st and 2nd generation Intel Core i5 processors are:

1. Architecture: 1st generation Core i5 processors were based on the Nehalem architecture, while 2nd generation Core i5 processors were based on the Sandy Bridge architecture, which is a 32nm microarchitecture.
2. Integration: 2nd generation Core i5 processors were the first to integrate the processor, memory controller, and graphics on the same die, making the package comparatively smaller.
3. Graphics Performance: 2nd generation Core i5 processors included new features to enhance graphics performance, such as Intel Quick Sync Video, Intel InTru 3D / Clear Video HD, and WiDi 2.0, which were not available in 1st generation Core i5 processors.
4. Performance and Power Consumption: 2nd generation Core i5 processors generally offer better performance and consume less power compared to 1st generation Core i5 processors.

In summary, 2nd generation Intel Core i5 processors offer improved performance, better graphics capabilities, and lower power consumption compared to their 1st generation counterparts.

Comparative Table: 1st Generation vs 2nd Generation Intel Core i5 Processors

Here is a table comparing the differences between 1st and 2nd generation Intel Core i5 processors:

The 2nd generation Intel Core i5 processors were introduced in 2011 and are based on the Intel Sandy Bridge architecture, which is a 32nm microarchitecture. They were the first Core i5 processors to integrate the processor, memory controller, and graphics on the same die, making the package comparatively smaller. In contrast, the 1st generation Intel Core i5 processors were introduced in 2010 and were based on the Intel Nehalem architecture. The 2nd generation processors also include several new features to enhance graphics performance, such as Intel InTru 3D / Clear Video HD, WiDi 2.0, and Intel Quick Sync Video, which were not available in the 1st generation Core i5 processors.
