"Difference to" or "difference with" or "difference from"
The correct options are:
Difference with AMD is...
Different to ...
Different from...
"Difference with AMD is..." used when stating a characteristic of AMD that is unique or different from other similar objects. No real comparison is being made.
"Different to" and "Different from" are used intentionally to make comparisons, between another similar object, and "AMD". But, if you aren't comparing two things, then the second two options cannot be used. They are used only when comparing.
