i am new to the x86 64 bit centos versions.

ive always used the 32 bit version on industrial type HP hardware

for those of you that are running x86 64 bit centos, other than specific
hardware issues, are you finding that 5.x centos is better than 4.x centos
for x86 64 bit processing?

does it matter in the amd vrs intel hardware differences what you choose to
use for centos version?

other things to make note of?

if i need to be more specific in the general-ness of the approach, please
let me know.

thanks in advance for feedback.

    the first generation of Intel Xeon's (based on P4 Prescott) that
    supported x86_64 were only slightly faster in 64bit mode than in 32bit
    mode, while the AMD Opterons were considerably faster. the newer Intel
    Xeons (based on Core2Duo) are quite a bit better.

    the latest Intel CPUs are generally faster at most/many things than
    AMD's CPUs, however, AMDs CPUs may still do better at scientific type
    programming that can't take advantage of the SSE3/etc 'dsp' style
    functions. Servers are as much a function of memory and IO bandwidth
    as anything, so there's many factors.

    My opinion is to first determine a few issues.

    How much RAM will it need? If over 3GB of physical RAM, consider 64
    bit.
    Are there third party applications you need to run on it? If they are
    64 bit, that answers the question too. If 32 bit, are they supported
    on 64 bit OS? Do they have different versions for 32 and 64 bit?

    lots of good info to ponder back from those that responded.

    what i a getting at is, why would one use x86 64 bit Centos version 4.7 when
    one can get the same in x86 64bit Centos 5.2 or later version?

    is there a reason to stay with the older version other than for specific
    deprecated hardware issues or something else?

    is 64 bit Centos 5 just plain better OR would some of you choose 4.7 over
    5.x and why?

    No, IMO. If you install a new system then install CentOS 5. Version 5 is
    so old by now that all major applications should be supported there. The
    usual YMMV apply.
