About this tag
The am4 socket tag on WindowsForum.com covers discussion of AMD's AM4 CPU socket and how it differs from newer platforms. The tagged content explains the physical design distinction between AM4 and AM5: AM4 processors use a pin grid array (PGA) layout with pins on the CPU itself, while AM5 moves to a land grid array (LGA) design with pins in the motherboard socket. The discussion also touches on compatibility considerations and safe installation practices when handling pinned processors. This is useful reference material for anyone building, upgrading, or troubleshooting an AMD desktop system and wanting to avoid bent pins or mismatched parts.

AM5 processors are flat, and the pins sit in the motherboard socket. PGA vs. LGA: where the pins are Both designs make the...
