I am not sure - I think Xeon is a modification of a basic chip design
and so current Xeons are PIV like while previous ones were PIII like.

There is no issue about Xeon chips.  The only issues we are seeing and
they are mostly worries rather than known issues are with the latest
operating systems (RedHat 9 now being gone but that is what we use)
and compiler revisions (some GNU 3.3.x have had reported failures and
an issue we worked around showed up with the latest fedora kernels).
