Even ancient 8087 FPU had 80-bit floating-point registers, although
8086 was a 16-bit CPU
Yes, my mistake, apologies.
It is integer calculation which could benefit from 32-bit to 64-bit
transition.
Okay, so, what about a 32-bit app on a 64 bit CPU vs. the same app
compiled for that target 64-bit CPU? Will the latter work faster or
no?
This is depends on many things. In some cases poorly-written code might
work on 64-bit CPU slower then compiled into 64-bit application.
In some cases it could work faster.
You might want to check your particular case with the Shark
