EPYC chips also come with integrated ethernet, but I don't think any vendors make use of that, either, not even the EPYC Embedded (3000-series). My Supermicro M11SDV-8CT-LN4F with an EPYC 3201 has 4x1Gbps Intel ports (+1x1Gbps Realtek for IPMI) even though the chip provides 4x10Gbps ports. I've read the issue is that motherboard designers can't be bothered to redesign around the integrated controller; easier to just continue slapping Intel or Realtek controllers on the board. That seems to be a big hurdle for AMD--they don't have enough volume to motivate much of the industry to make the best of what AMD offers. And when it does happen, there's a much longer lag time.
