Plug in a Second-Generation Intel Core i7 Processors with an LGA 1155 Socket

The Intel Core i7 is a family of CPUs, or central processing units, produced by Intel. The CPU is the processor of computer data, and the CPU’s processing speed determines how much data it can handle at a single time. Your favorite video games, software programs, and multimedia files all rely on the central processor in some capacity.

What type of architecture is the second-generation i7 based on?

The second-generation Core i7 processor is based on the Sandy Bridge architecture. The architecture refers to the internal design of the chip. Sandy Bridge is manufactured using a 32-nanometer-scaled process. This refers to the size of the components placed on the chip. The front-side bus of previous processors was replaced by Intel QuickPath Interconnect technology, which improves the communication speed and reduces latency time by creating high-speed, point-to-point links between individual circuits on the chip. Sandy Bridge is the last Intel architecture to support Windows Vista.

What are some features of the second-generation Intel Core i7?

The second-generation Core i7 processor family is defined by the following characteristics:

  • Number of cores: Most Sandy Bridge processors have four cores. Each core essentially acts as a separate processor. As the number of cores increase, the CPU can handle more work in parallel. Hyper-threading technology further improves parallel processing by creating two virtual cores for every physical core present.
  • Clock speed: Most Sandy Bridge processors have a 3.4 GHz or 3.5 GHz clock speed per core. Intel's Turbo Boost technology will incrementally increase the clock speed beyond the base frequency based on the demands of the software. It can keep boosting the clock speed for as long as the heat and power consumption are kept within normal levels.
  • L2 and L3 cache: The CPU cache is a small pool of speedy memory embedded in the CPU. It stores the most important and frequently used data. Since the memory is located next to the microprocessor, it can save time and can speed up operations. Intel's Smart Cache technology allows the memory to be shared between cores, so it is more efficiently used.
  • Thermal design power: This measures the maximum amount of heat that the processor can safely dissipate.
  • GPU model: All Intel CPUs are paired with a specific, integrated graphics processor. An integrated GPU is manufactured on the same die as the CPU, which allows them to share resources. It tends to be less powerful than a dedicated GPU. However, it is possible to use a dedicated graphics card instead of an integrated one.

What is an LGA 1155 socket?

The socket, which is located on the motherboard, provides a physical and electrical connection between the CPU and the rest of the circuit board. The LGA 1155 socket, also known as Socket H2, is only used by Sandy Bridge and certain Ivy Bridge processors. The Sandy Bridge-E architecture uses the LGA 2011 socket instead. Make sure to match the socket with your specific motherboard.
