Why AMD processor has pins and the Intel processor does not pin in it?

Intel and AMD are leading Computer Processor manufacturers in the market. Intel develops the processor themself whereas AMD processors are manufactured by TSMC. With the rapid development of technology, various types of CPU sockets are introduced like LGA, PGA, BGA.Intel uses a PGA socket and AMD mostly uses an LGA socket. In short, LGA Socket has pins in the socket itself and the PGA socket has no pin in the socket but it is on the processor itself

Now let's discuss the topic "Why AMD processor has pins and the Intel processor does not pin in it?".

AMD processor or Intel Motherboard processor Socket has the pin in any way because pins are needed for establishing electrical contact between processor and motherboard.

AMD Processor - Pin on CPU not on Socket

AMD Processor mostly uses PGA (Pin Grid Array) socket from the beginning. Here, Processor itself has pins in it and the processor socket doesn't have. When you fit the processor in the processor socket, pins get inserted into the holes of the socket. AMD is using PGA design-based processors in their Ryzen 3,5,7,9 and Athlon processors.


Advantage of Pin in Processor or PGA Design

1 Motherboard will be more durable because there will be less chance of damaging motherboard due to misalignment of CPU. Here, Motherboard is more durable.

2 If pins slightly bend in the processor because there will be sufficient gaps between each pin to correct them which provides better repairability.
3 Pin in the processor are thicker and will be easier to install.

Intel also used to use a PGA socket in the older motherboard which later started used LPA socket.

Intel Processor - Pin on Socket not on CPU

Intel Processor uses LPA(Land Grid Array) socket in all of the CPUs since 2004. Here, Processor itself doesn't have pins in it and the socket has pins.

Intel first processor using an LGA socket is Pentium 4 505 released in December 2004


Advantage of Pin in Processor Socket or LGA Design

1 There will be less chance of damaging the Processor because you should not have to handle pins in the processor. Here, the CPU is more durable than the motherboard.
2 If anyway Socket pins are broken then replacing the motherboard will be cheaper than replacing the processor itself.
3LGA pins are built in the processor sockets and the physical size of those pins are comparatively smaller than PGA pins so more pins can adjust in the same amount of space in LGA based processor. If more space then will be more contact between socket and processor and that helps in introducing stable power delivery and high-speed features.

4. There will be less leakage of electrical current.

5 LGA processors are easier to remove or replace even after many years of usage. 

6 It is said that the LGA socket is a more secure socket.LGA provides a much firmer and safer anchorage, putting pressure on the pins and ensuring a more evenly distributed load on the pins.

Intel uses LGA design for all processor ranges: servers, desktops. For a high-end system, AMD is also using LGA design. For high-end desktop PC, AMD has a Threadripper CPU that uses TR4 Socket and that socket uses LDP designs also for servers, AMD has an epic lineup that uses LDP designs.

From the consumer perspective, it is to note that whether it has pins in the processor or pins on the processor socket, the performance of the CPU does not get affected. Both of them has up and downside. But LGA socket will be sure more preferable in the future because the number of connection points will grow in the future, AMD will have to leave the PGA socket in order to keep the CPU small.

Are AMD Sockets compatible with Intel?

Ans: No, you cannot use an Intel processor in AMD sockets and vice versa.

Why Processor has many Pins?

Ans: Because it is required for lots of power and signals.

Why does AMD use Pin on Motherboard Socket in Threadripple Processor?

Ans: As we know Threadripple processor is used in high-end computers they require a large number of pins for getting all the functionality like supply voltages, buses, channels, cores, and many more. It has altogether 4094 contacts between CPU and CPU sockets and if maintain 4094 contacts by using 4094 pins then CPU size and CPU socket may require a larger size which increases the cost of production.

Also, this Threadripple processor is an expensive one and if it has pins in the CPU then it will be difficult to handles and accidental damage would be heightened.
