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