Nvidia's MSRP is full of shit and has been for a long time. You see it with desktop GPUs all the time, even before the AI boom, where Nvidia would make up an MSRP but not offer a card at that price themselves, and none of the AIBs would, either, except for some token amount that rapidly sold out and were never restoked.

If we look at what you can actually buy the 64GB RTX Spark is $4,500 and the 128GB one is $7,000: https://eshop.asus.com/us/31150-us-cnf-auto.html & https://www.dell.com/en-us/shop/laptop-computers/spd/xps16dx...

Hell there doesn't seem to be an RTX Spark that's sub $3,300 when considering the 32GB models even. $2,399 is pure fiction.

If datacenters aren't lining up to buy 64GB DGX Sparks for $5,000, what makes you think they'd be interested in 24GB RTX Sparks with fewer cores and less attractive form factors for almost half that?

And if there's a market for a DGX Spark configuration with a higher compute-to-RAM ratio, why isn't Nvidia offering it?

My best guess is that the entry-level Sparks are mostly intended for people who would otherwise be in the market for a traditional high-end laptop, who might be enticed to spend a few hundred more for at least the promise of local AI, while the higher-end models are intended for more serious AI development.

With that said, it's not hard to imagine there isn't nearly as large a built-in market for high-end SFF Linux PCs as there is for high-end Windows laptops.

Sure, but if you think it's insane to buy a DGX Spark for a datacenter, then it's equally insane to buy an RTX Spark (which is the exact same SoC just with less networking and a screen) for the datacenter.
