The dgx sparks and strix are very similar and the strix is a lot cheaper, almost half.

I hated the strix. It was fun to tinker with but even though I got “good” speeds with gpt oss 120 (50 tokens a second) it was still painfully slow for anything.

Just chatting was ok, say hi it responds back. Anything agentic or even real work you can see the problems with slow prompt processing.

For example I wrote a cli tool called please. So I can “please stop process on port 8000” and it would ask the llm for the command to do it and allow you to execute it by just pressing one.

Very small context, 1000 tokens at best. When pointing to a cloud api using same model it takes a second or so to get a response. When using strix halo it would take around 10 seconds.

The amount of context used to answer this simple query should be tiny yet it was still 10x slower than using the cloud. This is an incredibly simple task too. Image generation and coding or any other agentic task was so slow it was unusable. I thought about using it just to handle small model for reasoning or other tasks and it just becomes a bottle neck.

I was hoping using a 3090 via egpu would help the prompt processing part but it was just too slow when they were forced to work together.
