Poor performance on Pentium 4 against AMD machine

HI,
We had a database on an AMD machine. We ran SQL queries
there and performance were fine.
At a certain point, we moved the database to a Pentium
machine (backup and restore).
And now, on the Pentium machine we get performance on the
same SQL queries which are 2-3 time slower.
Using SQL Profiler we noticed that the disk-read takes
the majority of the time.
We tried to switch disks but no change in performance.
Does anyone have any idea of what could be the reason?
Thanks,
Danny.What disk subsystem is in use in both machines? What RAID levels, SCSI,
number of disks?
