There's a ton of spam on ebay currently with configs of the 512gb ram variant going for sub $4k. Those are all scams/spam. You can tell instantly because the seller's account is/was created this month 2026.
The $20k+ listings aren't selling but what's interesting is technically, $20k for 512gb ram is still less than $40/gb ram on a single device. Compare that to a Nvidia spark with 128gb ram selling at $4k+ or if you're lucky, you snagged one for ~$3500. That's $31.25/gb
The retail on the 512gb was $9500 and after tax if you don't ship to a sales tax free state makes it only $20/gb ram.
I'm curious what price apple's newest studio variant will be priced at per gb ram but I recently bought a "refurb" from a reputable seller I've purchased many laptops from in the past at $13,750 which still put the 512gb at a $27/gb ram price point.
I'm bullish on local models especially due to gemma4. Good luck out there!
Why though? Are you managing a fleet of headless Mac Studios? You mention LLMs, but today's Mac hardware really isn't great as soon as you use bit larger contexts, so I'm guessing it's not that either?
It would be interesting to see if this is getting worse or better.
