We must be twins, i've got the same three working in a cluster.
I was really excited to see where the GB300 Desktops end up, with 768gb ram but now that data is leaking / popping up (dell appears to only be 496gb), we may be in the 60-100k range and that's well out of my comfort zone.
If Apple came out with a 768gb Studio at 15k i'd bite in a heart beat.
I suspect they'll still want to offer it given the push they've been making over the last year with RDMA. My guess is the 512gb or larger studio will largely be a byproduct of the systems they're designing for their own AI efforts in the datacenter. I don't think this is the end of it for the longer term.
It gets weirder when they train you how to evade polygraphs as part of your role.. only to have you take one for your re investigation and to be asked "have you ever tried to evade a polygraph" or something along those lines. Of course you're not in a SCIF and your training or having been exposed to that training may in fact be classified. Quite the pickle..
