We did some benchmarking of our specific code on various HW.  The 
differences are quite staggering.  Code A would run the fastest on 
processor X, while slowest on processor Z.  Code C would be the exact 
opposite.  Considering execution times, the code that would be run, price 
and previous experience we ended up ordering a 128 CPU Opteron cluster as 
an addition to our Athlon, Alpha and XEON cluster farm.
  
Actually I have a dual Opteron 1U machine with serial ATA RAID on my desk 
right now.  Running FC2 64 bit kernel it outperforms Athlon 2800+ running 
some floating point code.  And its the cheapest Opteron at 1394.404 MHz.  

If you are seriously interested in this area, take a look at the InfoWorld 
February 2, 2004 article about 2.6 Linux kernel.  There are lot of things 
besides just the HW.
