The kernel and developer tools have standardized on "x86_64" for the name of the Mach-O architecture
AMD64" is the name chosen by AMD for their 64-bit extension to the Intel x86 instruction set. Before release, it was called "x86-64" or "x86_64
This was the original paper describing the Linux x86-64 kernel port back when x86-64 was only available on simulators.
The read/write speed of a hard drive is much slower than RAM, and the technology of a hard drive is not geared toward accessing small pieces of data at a time. If your system has to rely too heavily on virtual memory, you will notice a significant performance drop. The key is to have enough RAM to handle everything you tend to work on simultaneously.
On x86-64 versions of Windows, the FS register has been replaced by the GS register.
The x87, MMX, and 3DNow! instruction sets are deprecated in 64-bit modes.
There's a point of diminishing returns where adding more RAM won't give you better system performance.
There is, however, a point of diminishing returns at which adding memory to the server may not be justifiable based on price and performance.

Status: The kernel, compiler, tool chain work. The kernel boots and work on simulator and is used for porting of userland and running programs
