DeepSeek V4.1 Flash on 4x DGX Spark: my numbers vs Patrick Moorhead's results via Wccftech.

A couple of weeks ago I read this Wccftech article about Patrick Moorhead's 4 Spark setup.

Key points

  • I meant to post this a few days ago but ran some more tests first, and then my workstation had a problem after a kernel and NVIDIA driver update.
  • Initially I thought this Patrick Moorhead guy ran these benchmarks and was interested in the setup.
  • I'm just severely disappointed over the lack of info, and over the misreported memory requirement in the Wccftech article.
  • DeepSeek-V4.1-Flash doesn't fit comfortably on 4x Sparks.
