Yup. AMD has an on-die 10gbe controller that would show up as AMD. Anything that says Intel/Broadcom/realtek/etc are off chip and something the MFG put on the motherboard which adds cost.
- kentonv 6y agoHmm. I'm speculating, but I'd guess that tossing on the same external controller that they've put on a million other motherboards in the past probably actually saves cost, vs. designing something unique to expose the on-die controller. I wonder what the performance impact is, though. I'd guess (very naively) that an on-die controller would perform better.
- wtallis 6y agoMy guess is that the Intel Ethernet drivers are seen by the customers as very tried-and-true, and how to tune them is well-documented. AMD's Ethernet drivers are relatively unknown and unproven, and it's easy to imagine that they could perform worse. That could easily make up the difference in cost between an external PHY vs an external MAC+PHY.
