AMD64 refers to both Intel and AMD chipsets that are 64bit x86. While you are right that there is also the term "x86_64" in common use, AMD64 is the actually more standard name (as well as the term specifically used in the Go ecosystem eg $GOARCH env var and build parameters for cross platform sources)

Further to that point, I didn't detect any confusion from others in this thread that AMD64 excluded Intel chips. Where they were talking about AMD64 specific code they were saying that Go code targeting other architectures (eg arm, mips, s390x and ppc - to name a few. Go supports an impressive number of architectures[1]) would still use their respective fork() code rather than this new fix.
