Does anyone have an idea how this might perform on a DGX Spark at longer contexts? I've been trying to investigate their performance with these medium-sized MoE models, but I'm seeing a lot of incomplete and conflicting information. The 273 GB/s bandwidth looks awfully bad on paper...

A single Spark alone is not worth the price. You are paying $1000 just for networking equipment you aren't using. At 2x it starts to maybe become worth it if you don't want to deal with Apple. Outside of the newest Macs, I can't think of anything else you can get 256 GB ~550 GB/s memory bandwith for $8200. Even at 3-4 Sparks it scales relatively well.

With 2x Sparks, I am getting 40 t/s. I'd guess that without MTP you'd get 12-15 on 1 Spark, maybe 20 with MTP?

Given the new architecture, speeds are harder to estimate. Max would be ~40 tok/s.

I can run Deepseek flash 0731 version (ds4, esl3) on single DGX spark. getting around ~20 tok/s. It's great. Quantized version of this model would probably run on the DGX spark. I am excited to wait for quantized models that fits in single DGX spark.
