I recently bought a 64 bit machine and have 10.3 loaded . It seems very fast.
I am trying to appraise if the advantages of having some software not work
because of driver issues is worth it.
Has anyone run benchmarks on an identical system with 32 bit vrs 64 bit?
Do we have a list of software that is known not to work on 64-bit?
Any defined group tracking this and championing gettin the remainder
fixed.
I know this is a generalized question but I am just trying to appraise
the gain vrs pain of deciding to stay with 64-bit ?
Most data isn't 64-bit. In fact, a large chunk of it
is still 16-bit, and even 8 bit (ASCII text, for example).
Most of the speed increase you are seeing is from:
1) the faster clock speed of your new CPU compared
to the last one you had.
2) wider data buses into and out of the on-chip cache.
3) floating point operations (where applicable).
You won't see a significant difference between
32-bit and 64-bit system performance until you
are running some software which uses lots of
64-bit integers, or is very intensive in
floating-point operations.
Cheers,
Bob
