Dell fixing issues instead of creating new ones? That's a new one for me. Would rather still not deal with their firmware updaters thought.

Give them a chance, I’m sure they’ll add new issues in one of their monthly bios updates.

You can get two Strix Halo PCs with similar specs for that $4000 price. I just hope that prompt preprocessing speeds will continue to improve, because Strix Halo is still quite slow in that regard.

Then there is the networking. While Strix Halo systems come with two USB4 40Gbit/s ports, it's difficult to

a) connect more than 3 machines with two ports each

b) get more than 23GBit/s or so per connection, if you're lucky. Latency will also be in the 0.2ms range, which leaves room for improvement.

Something like Apple's RDMA via Thunderbolt would be great to have on Strix Halo…

The primary advantage of the DGX box is that it gives you access to the nVidia ecosystem. You can develop against it almost like a mini version of the big servers you're targeting.

It's not really intended to be a great value box for running LLMs at home. Jeff Geerling talks about this in the article.

Exactly this. I'm not sure why people keep drumming the "a Mac or Strix Halo is faster/cheaper" drum. Different market.

If I want to do hobby / amateur AI research or do stuff with fine tuning models etc, learn the tooling. I'm better off with the DG10 than AMD or Apple's systems.

The Strix Halo machines look nice. I'd like one of those too. Especially if/when they ever get around to getting it into a compelling laptop.

But I ordered the ASUS Ascent DG10 machine (since it was more easily available for me than the other versions of these) because I want to play around with fine tuning open weight models, learning tooling, etc.

That and I like the idea of having a (non-Apple) Aarch64 linux workstation at home.

Now if the courier would just get their shit together and actually deliver the thing...

As you allude, the prompt processing speeds are a killer improvement of the Spark which even 2 Strix Halo boxes would not match.

Prompt processing is literally 3x to 4x higher on GPT-OSS-120B once you are a little bit into your context window, and it is similarly much faster for image generation or any other AI task.

Plus the Nvidia ecosystem, as others have mentioned.

One discussion with benchmarks: https://www.reddit.com/r/LocalLLaMA/comments/1oonomc/comment...

If all you care about is token generation with a tiny context window, then they are very close, but that’s basically the only time. I studied this problem extensively before deciding what to buy, and I wish Strix Halo had been the better option.

I've got the Dell version of the DGX Spark as well, and was very impressed with the build quality overall. Like Jeff Geerling noted, the fans are super quiet. And since I don't keep it powered on continuously and mainly connect to it remotely, the LED is a nice quick check for power.

But the nicest addition Dell made in my opinion is the retro 90's UNIX workstation-style wallpaper: https://jasoneckert.github.io/myblog/grace-blackwell/

I just want a standard, affordable mini PC that looks like this one. Or better yet, with the brown accents normally found on recent PowerEdge systems.

Zotac has a bunch of x64 mini PCs that use a similar hexagonal styling.

DGX Spark at $4,000 is a bad deal with only 273 GB/s bandwidth and the compute capacity between a 5070 and a 5070 TI. And with PCIe 5.0 at 64 GB/s it's not such a big difference.

And the 200 GBit/s QSFP... why would you stack a bunch of these? Does anybody actually use them in day-to-day work/research?

I liked the idea until the final specs came out.

I assume they didn't fix the memory bandwidth pain point though.
