Socket LGA1155, also known as Socket H2, is a CPU socket developed by Intel for use with its second-generation Core processors, also known as Sandy Bridge. These processors were released in 2011 and offered improved performance and energy efficiency over the previous generation.
The LGA1155 socket has 1155 pin contacts, and supports dual-channel DDR3 memory, which offers higher bandwidth and lower power consumption than DDR2, the memory type used with the previous LGA1156 socket. It also supports the use of integrated graphics processors (IGP) on the CPU, which can reduce the need for a separate graphics card and help to save power.
One of the main advantages of the LGA1155 socket is its support for Intel’s Turbo Boost technology. This technology allows the processor to automatically increase its clock speed when needed, which can improve performance in demanding tasks such as gaming and video editing. Additionally, it also support Hyper-Threading technology, which allows for better multitasking and improved performance on multithreaded applications.
The LGA1155 socket also supports Intel’s Quick Sync Video technology, which can be used for fast video encoding and decoding. This can be especially useful for users who frequently work with video and want to improve their workflow.
Another advantage of the LGA1155 socket is its support for Intel’s Advanced Vector Extensions (AVX), which can improve performance in applications that rely heavily on floating point calculations, such as scientific simulations and image processing.
Overall, the Socket LGA1155 is a solid choice for users looking to build a powerful and efficient system. It offers a range of advanced features, such as support for Turbo Boost, Hyper-Threading, Quick Sync Video and AVX, that can help to improve performance and energy efficiency. It also backwards compatible with some of LGA1156 processors.
