A CPU (Central Processor Unit) is a computer’s brain that performs all of the computations and processes needed to execute instructions.
The CPU is linked to the motherboard through a socket, allowing it to interface with other system components. The physical and electrical parameters of the connection between the CPU and the motherboard are determined by the socket type.
In this article, we will go through the various CPU socket types.
What Are The Types Of CPU Sockets?
PGA (Pin Grid Array) Socket:
PGA is the most common socket type for CPUs. A PGA socket, it has a grid of pins that make contact with the socket on the motherboard. PGA sockets are easy to install and replace. They are commonly used in desktop and server systems.
LGA (Land Grid Array) Socket:
LGA is a newer socket type that is used by Intel processors. In an LGA socket, the pins are on the motherboard, and the CPU has flat contacts that make contact with the socket. LGA sockets are more durable and easier to manufacture than PGA sockets. They are commonly used in high-end desktop systems.
BGA (Ball Grid Array) Socket:
BGA is a socket type used in laptops and other portable devices. In a BGA socket, the CPU is soldered directly onto the motherboard, making it difficult to replace or upgrade. BGA sockets are used in small form factor systems where space is at a premium.
SPGA (Staggered Pin Grid Array) Socket:
SPGA is a socket type used in some older CPUs. In an SPGA socket, the pins are staggered, making it easier to align the CPU during installation. SPGA sockets are not commonly used anymore, as they have been replaced by newer socket types.
FC-PGA (Flip-Chip Pin Grid Array) Socket:
FC-PGA is a socket type used in some older AMD processors. In an FC-PGA socket, the CPU is flipped upside down, and the pins make contact with the socket on the motherboard. FC-PGA sockets are not commonly used anymore, as they have been replaced by newer socket types.
In conclusion, while building or updating a computer, the CPU socket type is a crucial factor. The most popular socket types for desktop computers are PGA and LGA, whereas BGA sockets are utilized in portable devices. Older socket types like SPGA and FC-PGA are no longer widely utilized. It’s crucial to pick a CPU that works with the motherboard’s socket type while making your selection.
Frequently Asked Questions
Can I use an LGA CPU in a PGA socket?
No, because the pins and contacts are different, you cannot put an LGA CPU in a PGA socket.
Can I use a BGA CPU in a PGA socket?
No, because the CPU is soldered directly to the motherboard, you cannot put a BGA CPU in a PGA socket.
Can I upgrade the CPU to a BGA socket?
Because the CPU in a BGA socket is soldered directly to the motherboard, upgrading the CPU is difficult. Replacing the CPU would need the replacement of the complete motherboard.
Can I use an Intel CPU in an AMD motherboard?
No, you cannot use an Intel CPU in an AMD motherboard, as they use different socket types.
