Contributed by grey on from the reviews gone right dept.
Here is a nice article about the different free UN*Xes available on AMD64 machines.
They have a number of nice quotes on OpenBSD/AMD64, including this: 'nearly all of the programs in the Ports tree compile for 64-bit without any problems [...] The reason for the breakage being so minimal is not an accident -- the OpenBSD Ports contributors strive for quality as a primary goal.' (the last part being from Peter Valchev). Overall, a nice review.

Programs are not faster because they are 64-bit. AMD64 is generally faster because of the availability of extra registers, but it has been shown time and again (especially on sparc) that 32-bit architectures move less data and thus run faster.

A longer word length doesn't necessarily mean that it takes longer to move data. It depends on how that data is moved around, how wide is your data path, what's the bandwidth of the channel...
Even then sometimes it makes sense from the point of actual instruction execution time to pass even larger chunks of data around. Enter SIMD, MIMD, vector processing...

Err... Sorry, the title should read 'Newsforge article on AMD64...'. My fault: I probably did not re-read this submission as I should have. All my apologies.
And yes, it's lame correcting your own submission like this! ;-)
