Fastest Qwen 3.5 122B Int4 recipe on DGX Spark tested and published on Spark-Arena

Hello @0rand Any chance you could explain the differences between this version and the one by @Albond here: Qwen3.5-122B-A10B on single Spark: up to 51 tok/s (v2.1 — patches + quick-start + benchmark)

Is one faster but lower quality, or do they support different context lengths, or are there other differences? Note I am asking as a single spark user, not dual.

Thank you
