       | for me. Would rather still not deal with their firmware updaters
       | thought.

       | 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...

         | 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...

             | real tinkering it can't be beat.
             | 
             | I've used it to fine tune 20+ models in the last couple of
             | weeks. Neither a Mac or Strix Halo even try to compete.

         | 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:

       | IMHO 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 2x 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.

         | The memory bandwidth limitation is baked into the GB10, and

         | 
         | I'm really curious to see how things shift when the M5 Ultra
         | with "tensor" matmul functionality in the GPU cores rolls out.
         | This should be a multiples speed up of that platform.
        
           | storus wrote:
           | My guess is M5 Ultra will be like DGX Spark for token prefill
           | and M3 Ultra for token generation, i.e. the best of both
           | worlds, at FP4. Right now you can combine Spark with M3U, the
           | former streaming the compute, lowering TTFT, the latter doing
           | the token generation part; with M5U that should no longer be
           | necessary. However given RAM prices situation I am wondering
           | if M5U will ever get close to the price/performance of Spark
           | + M3U we have right now.
