Article doesn't seem to mention price which is $4,000 which makes it comparable to a 5090 but with 128GB of unified LPDDR5x vs the 5090's 32GB DDR7.
A 5090 is $2000.

#22This is insanely slow given its 200+GB/s memory bandwidth. As a comparison, I've tested GPT OSS 120B on Strix Halo and it obtains 420tps prefill and >40tps decode.

And about 1/4 the memory bandwidth, which is what matters for inference.
For inference, the DGX Spark does not look like a good choice, as there are cheaper alternatives with better performance.

#24It would be interesting to swap out Ollama for LM Studio and use their built-in MLX support and see the difference.

A 5090 is $2000.
Still, a PC with a 5090 will give in many cases a much better bang for the buck, except when limited by the slower speed of the main memory.
The greater bandwidth available when accessing the entire 128 GB memory is the only advantage of NVIDIA DGX, while a cheaper PC with discrete GPU has a faster GPU, a faster CPU and a faster local GPU memory.

Well, that’s disappointing since the Mac Studio 128GB is $3,499. If Apple happens to launch a Mac Mini with 128GB RAM it would eat Nvidia Sparks’ lunch every day.
People that keep pushing for Apple gear tend to forget Apple has decided what industry considers industry standards, proprietary or not, aren't made available on their hardware.
Even if Metal is actually a cool API to program for.

#28Earlier quoted context omitted.
FYI you should have used llama.cpp to do the benchmarks. It performs almost 20x faster than ollama for the gpt-oss-120b model. Here are some samples results on my spark: ggml_cuda_init: found 1 CUDA devices: Device 0: NVIDIA GB10, compute capability 12.1, VMM: yes | model | size | params | backend | ngl | n_ubatch | fa | test | t/s | | ------------------------------ | ---------: | ---------: | ---------- | --: | ----…
I see! Do you know what's causing the slowdown for ollama? They should be using the same backend..
Or you can just ask the ollama people about the ollama problems. Ollama is (or was) just a Go wrapper around llama.cpp.

#29I wonder why they didn't test against the broadly available Strix Halo with 128GB of 256 GB/s memory bandwidth, 16 core full-fat Zen5 with AVX512 at $2k... it is a mystery...
tl;dr it gets absolutely smashed by Strix Halo, at half the price.
