"DGX Spark has only half the advertised performance"

I've been skeptical of NVIDIA products since playing with my Nano Jetson . The lack of various developers' success across different forums is striking. Also, the lack of actual support is striking (for example, it requires a downgraded Ubuntu host machine to receive flash updates).

My experience with Raspberry Pi products is a stark opposite. They just work.

As someone old to software but new to hardware, I'm not sure what to make of this.

I think statements like this stem from a miss-understanding mostly fueled by the DGX Spark's price and partly by Nvidia's marketing.

The DGX Spark is essentially a developer board for people that need to develop for Nvidia's newest gen hardware but cannot get the real thing because of lacking availability (not primarily price). Ignoring Nvidia's ambiguous sales message and going by the technical data it is clear the DGX Spark is not for top performance production workloads. It's a development tool.

Seems to be due to a misunderstanding of the expected performance of the DGX Spark: https://xcancel.com/Lasurak/status/1983178709348516238

The GPU part of it is effectively an RTX 5070, with lower bandwidth memory.
