I originally wrote more, but hate when people simply copy stuff from the internet and don't do their own research, so erased that.
So starters;
Architecture is very different (how they organize their components, and how it does the math), and their approach to implementation as a card is very different (small chip with modular combinations in both directions vs bigger chip with less options), this influences their production, launch as well as planning throughout the life cycle.
Check launch reviews and then articles about production, that should give you more than enough to figure it out for an essay.
And most importantly they are both similar, just different, neither is objectively 'better', especially since the theoretically better approach to something (be it architecture or production/implementation) may not turn out to be so due to other concerns (and that applies at so many levels of this it's ridiculous).
An essay on how they different yet the same focusing just on the reason they end up the same would be long enough on it's own (research paper length).
