That assumes KolibriOS or any major component is pinned to one core and one cache slice instead of getting dragged between CCDs or losing memory affinity. Throw actual users, IO, and interrupts at it and you get traffic across chiplets, or at least across L3 groups, so the nice 'everything lives in cache' story falls apart fast.

Nice demo, bad model. The funny part is that an entire OS can fit in cache now, the hard part is making the rest of the system act like that matters.
