How much of that 64 GB is in use at the same time though? Caching not recently used stuff from DRAM out to an SSD isn't actually that slow, especially with the high speed SSD that Apple uses.

Right. And to me, this is the interesting part. There's always been that size/speed tradeoff ... by putting huge amounts of memory bandwidth on "less" main RAM, it becomes almost half-ram-half-cache; and by making the SSD fast it becomes more like massive big half-hd-half-cache. It does wear them out, however.
