Your words “it’ll speed up swapping” may be key here. There’s also likely to be some other tricks Apple has come up with as well but we’ll have to see how that works out. I’m not sure there’s many people who need that much ram and this could be a direction the iMac Pro or Mac Pro take. It’s very interesting to consider. Apple is on to something and I’m also curious if anyone else is going to try the same approach. It’s just seems it’ll be much more effective in a one company does it all environment.
