ARM vs. PGA
Comparing 2 standards across 8 specifications. 8 key differences identified.
ARM is a family of RISC (Reduced Instruction Set Computer) processor architectures, originally developed by Acorn Computers in the UK starting in 1983 as the Acorn RISC Machine. Unlike Intel or AMD, ARM Holdings doesn't manufacture chips -- it licenses its architecture designs to companies like Qualcomm, Apple, and Samsung, who build their own chips around it.
PGA (Pin Grid Array) puts the pins directly on the processor package, with the socket providing holes instead -- the inverse of LGA. AMD used PGA for its mainstream desktop sockets for years, including AM4, before shifting its mainstream line to LGA with AM5 in 2022.
