    Are 64 bits really faster than 32?

    Sorry guys. I can't follow your drift. I'm not able to re-compile nor re-link the app. I just own the executable (.EXE) objects, along with the runtime libraries. If I had the .OBJ objects and the required libraries, I could relink the app. I asked the vendors if they could. The answer was NO...

    Are 64 bits really faster than 32?

    Ok, I realize that you can address memory beyond the 4GB barrier. But the 32-bit apps would take advantage of that extra addressable memory? I have an US$15,000 engineering application which makes an extensive use of the 4GB installed memory. When running, it causes the OS (Win Vista Pro) to...

    Are 64 bits really faster than 32?

    I have heard that 64 bit architecture does not outperform 32 bit because 32-bit applications do not take advantage of the oversized processors since they run under a backward compatibility mode. To take advantage of the 64-bit the old 32-bit apps should be rewritten or at least recompiled. In...
