x:Bind vs TemplateBinding inside ControlTemplate

What is the difference between using TemplateBinding and x:Bind inside the ControlTemplate? On the document, it is mentioned that Function Binding and Twoway binding can be done through x:Bind. But is there any internal info that TemplateBinding is more lightweight than x:Bind? Is TemplateBinding better than x:Bind in terms of performance?

TemplateBinding is one-way mode, reduce the code behind generating and using, which makes it more lightweight.This is only my thought.I still have the same question.
