LGA vs. x86-64
Comparing 2 standards across 8 specifications. 8 key differences identified.
LGA (Land Grid Array) puts the pins on the socket rather than the chip -- the processor has flat contact pads instead of pins, reducing the risk of chip damage since a bent-pin problem falls on the cheaper motherboard rather than the CPU. Intel adopted it for desktop CPUs in 2004 with Socket 775.
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.
