I think the idea is that instead of spending an additional $4000 on external hardware, you can just buy one thing (your main work machine) and call it a day. Also, the Mac Studio isn’t that much cheaper at that price point.
In the list price, it's 1000 USD cheaper. 3,699 vs 4,699 I know a lot can be relative but that's a lot for me for sure.
The Mac Studio is a more appropriate comparison. There is not yet a DGX laptop, though.
I can do that with a laptop too. And with a dedicated GPU. Or a blade in a data center. I though the feature of the DGX was that you can throw it in a backpack.
Why not?
