Annecdotal here but I've been buying studios with as much ram as possible. I probably got in one of the last orders for the m3 ultra 512gb ram officially from apple late February right before they took that config down. I know this because the very next day I went back to order more and couldn't.

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!
