The second half of your response is absolutely correct. However, none of that aligns with the definition of mismatched.Well, yes and no. The M5 Pro and Max are much more closely related to the M5 than they will be to the M6. So, I'd say MacRumors' terminology here isn't entirely inaccurate. What this would mean is that for certain specific actions, the M6 might perform better than M5 Pro, or in the very least, the M5 Pro wouldn't perform as much better as expected when compared to the M6 as opposed to the M5.

There is nothing unsuitable or incorrect about having multiple Mac mini models with processors from different generations. A customer will make a choice as to which fits their needs and they will have that one model with one processor. It will function perfectly and the fact that there are other models with different processors will have no bearing on the operation of their Mac mini.
