That’s not what I suggested. There is one processor and RAM setup across all (current model) iPads Pro. There are multiple processors and RAM configurations on the various MacBooks Pro (ugh, that sounds terrible to me — I much prefer MacBook Pros). So if the iPad Pro processor (or whatever metric he was referring to) is faster than all the MacBook Pro processors, then it would be perfectly normal to say the one singular is faster than the other plural.

It would be like saying the iPhone 11 Pro has a better camera than all the iMacs (which vary by model, but none are as good as the iPhone).
