I was surprised by this as well, but my results for a different memory bandwidth bound workload match what Dell is reporting: When testing a rome CPU at Netflix, I found I could serve 200+Gb/s of TLS encrypted video with 4nps, 192Gb/s with 2nps, and 184Gb/s with 1NPS.
My best guess was that I didn't fully understand the architecture of the IO die. Eg, there was some benefit to being local that I didn't understand fully.
