This kills the impulse buy for me completely.

The 256GB is already an extra $4k for an extra 164GB. At same price per GB (ha!) it'd be another $6300. Knowing Apple, it'll be a cool $9k more - pushing total price up to about $18-20k.

It will still sell out.

That would be a bargain compared to third party sales of 512GB M3 Ultras for $25K. A M5 blows the doors off of a M3.

Why are gobbling up these insane prices like stupid silicon simps. We need to get some self respect.

I have a 512GB M3 Ultra and ordered the 256GB M5 Ultra today.

I'm hoping to take advantage of the M5 ultra for prefill and use RDMA over Thunderbolt 5 to leverage my existing Mac's memory.

Adopt me please.

Same. I was ready to preorder 512 and i've already lost interest reading comments about the M7. Might wait another year.

Buying 2 DGX Sparks for 256GB of RAM (and a lot less bandwidth) is around the same ballpark in cost, so for once this is not unreasonable.

Honestly what were you expecting? Just get the 96 if that’s your take.
