Dear friend, before choosing between the Intel and AMD, you must to know that, u cannot cluster two host; one with intel base cpu and one with amd base cpu.
on the other hand, changing the infrastracture from AMD Based Systems to Intel Based Systems is very expensive.
With this hint, if you want to change the cpu infrastructure, it is better to know that AMD works properly on some conditions and Intel works properly on some other conditions, if you have not special condition for using CPU optimizely, as i think intel is a better solution as it comes with newer technology and partner with VMware too.
If this is hepful or correct, would u please mark it as "Helpful" or "Correct"?
Thank u
Saman
