The only way to be sure is to test your workload on the two different 
machines.

That said, we moved from AMD to Intel E series Xeon a year ago. We were 
using 8-core AMD devices not 12, and switched to 6-core Intel. The Intel 
devices were more attractive due to their (much) higher single-core 
performance. Another factor was a history of hardware bugs in the 
support chips used on AMD systems that we haven't generally seen with 
Intel. So all other things being equal, Intel brings less hassle, in my 
experience.
