The Blackwell and Strix Halo will be similar to each other and much slower than the number I'm getting on the dual V620 setup (I see about 10-15 t/s on my Strix Halo with this model at 8-bit quantization depending on context). Prefill is generally quite a bit faster on the DGX Spark and token generation slightly faster on the Strix Halo, as I understand it. But, there are better software efficiency improvements for the Spark line.
This model is far from usable on current AMD or Nvidia 128GB AI machines, IMHO, they just don't have the memory bandwidth, especially since it chews so many tokens for any task. If you want to run this specific model, two (or more) 32GB GPUs with decent memory bandwidth is the right way to do it. It doesn't benefit from the larger memory of the Strix Halo. There's enough room for full context and 8-bit quantized model in 64GB. But, it's really a terrible time to buy hardware. MoE models are a much better fir for the Spark and Strix Halo; you can run Laguna S2.1 (slowly) or one of the Qwen 3.6 MoE fine-tunes (pretty quick). Ling 3.0 Flash also looks promising. Nemotron 3.5 Lightning in the MXFP4 quantization absolutely flies on the Strix Halo at 65-80 t/s, but it's dumb. But, all of those are weaker than Qwen 3.8 27B for coding.
