If you claim to know anything about PCs, yes. They are the main competitor to Intel for commodity x86 architecture processors and were the original developer of the 64-bit instruction set for the x86 architecture in the early 2000s.

Edit: at the time, Intel thought the x86 instruction set was obsolete, so its strategy was to migrate to 64-bit with a new instruction set called Itanium. However they had trouble gaining adoption, and with AMD releasing their 64-bit x86 processors that pretty much killed Itanium for anything but niche applications. Until Intel released their own 64-bit CPUs, AMD was the supplier for x86 processors if you were doing something that required a lot of memory.
