Processors
PGA vs. x86-64
Comparing 2 standards across 8 specifications. 8 key differences identified.
Comparing:
PGA
x86-64
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.
x86-64 is the 64-bit extension of the x86 architecture, developed by AMD and first specified in 1999-2000 under the name AMD64, shipping in the 2003 Opteron. Intel followed with its own compatible implementation in 2004, initially branded EM64T and renamed Intel 64 in 2006.
