PGA vs. RISC-V
Comparing 2 standards across 8 specifications. 8 key differences identified.
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.
RISC-V is a free, open-source RISC instruction set architecture developed starting in 2010 at UC Berkeley -- unlike ARM or x86, it can be implemented without paying any licensing royalty. It's currently most common in microcontrollers and embedded systems, with higher-performance implementations for mobile, desktop, and server use still in development.
