Your 2019 Macbook also uses a different chassis, designed by Jony Ive. Apple knew it throttled the chips they used but shipped it anyways, presumably because Ive liked his thinness even when it results in a bendgate.

You'll note that Macbooks don't quite look the same after Ive left and his influence went away.

I don’t actually know. Last MBP I had was circa 2017 or so.

How are they different ?

Beefier. Bulkier. Quick google search says Intel 16" was 4.3 lbs whereas M4 16" is 4.7 lbs. Not a big difference you say but 1) it is going in the opposite direction where the newer product is bulkier and 2) imagine the years of thin-ness that would have been forced under a different regime.

I wonder how much of that is battery.
