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

The main differences between 1st generation and 2nd generation Intel Core processors are the microarchitecture and the performance improvements. Here are the key differences:

1. Microarchitecture: 1st generation Intel Core processors are based on the Nehalem microarchitecture, while 2nd generation processors are based on the Sandy Bridge microarchitecture.
2. Performance: 2nd generation Intel Core processors offer around 10-20% higher performance compared to the 1st generation processors. This improvement can be attributed to the new microarchitecture and optimizations.
3. Graphics Performance: 2nd generation processors include new features for enhancing graphics performance, such as Intel Quick Sync Video, Intel InTru 3D / Clear Video HD, and WiDi 2.0. These features were not available in the 1st generation processors.
4. Socket Compatibility: 1st generation Intel Core processors used sockets 1156 and 1366, while 2nd generation processors used the LGA 1155 socket.

In summary, the 2nd generation Intel Core processors offer better performance, new features for enhanced graphics performance, and socket compatibility compared to the 1st generation processors.
