32 bit vs. 64 bit


F

1. Can 64 bit software be used by a 32 bit processor?

2. Would it be wise to get a Windows Vista 64 bit PC?

3. What are the pros and cons?


Thanks.........

Yes, in my view. Even if you don't run 64-bit Vista now (and you may not
want to unless you are sure you can get 64-bit drivers for all your
hardware), it may be wise to get a 64-bit system and run 32-bit Vista on it
now. That will let you upgrade to 64-bit Vista in the future when drivers
for all your hardware becomes available.

3. What are the pros and cons?


Cons: Still poor driver support. Few 64-bit apps available.

Pros (regarding the 64-bit hardware): versatility for the future. Little
additional cost over 32-bit hardware

YES. Sooner or later games will be coming out optimised for 64-bit and
you will be ready for them.
All cons.......lack of drivers lack of software for the avg user lack
of games
These 'problems' will be fixed over time.

Cheers,

I would not get any Vista PC until SP1. Just the same, 64-bit capable is
about the only new hardweare available. There just is not much 64-bit
applications in the M$ part of the world.
Yes, in my view. Even if you don't run 64-bit Vista now (and you may not
want to unless you are sure you can get 64-bit drivers for all your
hardware), it may be wise to get a 64-bit system and run 32-bit Vista on
it now. That will let you upgrade to 64-bit Vista in the future when

I actually agree here, even in the Linux/Unix part of world the frameworks
and applications (with a few exceptions) are still few.
Cons: Still poor driver support. Few 64-bit apps available.

Pros (regarding the 64-bit hardware): versatility for the future. Little
additional cost over 32-bit hardware
So there it is for both M$ and the Linux/unix world that is based on x86
compatible systems. On the other hand Sun Solaris (a Unix variant) for
SPARC has a full cadre of well developed 64-bit tools, drivers, and
applications. And much is available for HP-PARisc, Open VMS (DEC Alpha),
and some MIPS 64-bit platforms (SGI IRIX comes to mind). DEC Alpha, SPARC
64-bit, and MIPS 64-bit are all well established to obsolete, time line
wise. Intel and M$ are just playing catch-up again. Don't believe me,
Google for it. And yes, I do know about Itamium II and SGI Altix. Look at
what is used to create the fastest 100 supercomputers in the world.
