x86_64
The 64-bit version of the x86 CPU architecture used by modern PCs and servers.
x86_64 (also called AMD64) extends the older 32-bit x86 to 64 bits, allowing far more memory and wider registers while still running x86 software. It's the default architecture for contemporary desktops and servers. It's one of the concrete build targets mzOS2 supports.
