What are LGA and PGA?

LGA stands for Land Grid Array and PGA stands for Pin Grid Array. LGA based CPUs have flat surface contacts where as the PGA CPUs have pins for interfacing with the motherboard. In the current market, Intel primarily uses the LGA technology whereas the AMD uses the PGA technology for their processors.

Is Ryzen a PGA?

PGA – mainly used by AMD now The latest Ryzen processors are still using PGA with the AM4 socket. However, AMD’s Ryzen Threadripper and EPYC processors have already moved onto a larger, brand new LGA 4094 socket (TR4/SP3).

Does AMD use LGA or PGA?

Like Intel, AMD decided to use LGA sockets for their higher pin densities, as a 1944-pin PGA would simply be too large for most motherboards.

What does PGA stand for in computers?

A pin grid array (PGA) is a type of integrated circuit packaging. In a PGA, the package is square or rectangular, and the pins are arranged in a regular array on the underside of the package. The pins are commonly spaced 2.54 mm (0.1″) apart, and may or may not cover the entire underside of the package.

Why AMD still use PGA?

AMD has long stuck with a pin grid array (PGA) for its CPU packaging. The other popular alternative is a ball grid array (BGA), which is widely used today, primarily in mobile devices. The reason we’ve not seen it much on desktop is because BGA designs actually see the chip soldered permanently to the socket.

Does AMD still use PGA?

Is Ryzen PGA?

What is PGA and LGA in processor?

LGA and PGA can be understood as opposites. LGA stands for land grid array and consists of a socket with pins on which the processor is placed. PGA, on the other hand, places the pins on the processor, which are then inserted in a socket with appropriately placed holes. Intel uses the former while AMD uses the latter.

What is a LGA socket?

An LGA socket is a type of central processing unit ( CPU) socket that uses the land grid array style of integrated circuit packaging. Several processors, or CPUs, possess pins that go into the socket’s pin holes to connect them with the motherboard.

What is a BGA socket?

A BGA socket is a central processing unit (CPU) socket that uses a type of surface mount-based integrated circuit packaging called ball grid array.
