Intel NICs are 5-10x that price. I'm not sure why, but my suspicion is that it has to do with driver support and/or interoperability.
- Palomides 3y agoI run mellanox connectx3 cards, they work immediately with no extra drivers on windows 10/11 and every linux I've tried mellanox is/was quite good at getting code upstreamed maybe I need to do my own blog post about my pile of computers...
- TacticalCoder 3y ago> maybe I need to do my own blog post about my pile of computers... Yes, several of us love to read about that! I haven't switched to 10 Gbit/s yet...

- gregors 3y agowould love to read this!
- Hikikomori 3y agoMellanox works fine.
- hamandcheese 3y agoGotcha. Why the price discrepancy then?
- Hikikomori 3y agoAre you comparing new Intel cards to old mellanox cards on ebay? If not idk why, I have not compared them myself, some feature maybe? Cost doesn't always make sense either.
- hamandcheese 3y agoIm just comparing the prices I see when I search ebay for "40gbe nic" vs "40gbe nic intel", making no effort to compare features.
- petronio 3y agoI can't answer definitively, but I was looking for SFP cards recently and the older cards don't really support ASPM. The cards themselves aren't power hogs, but they keep the CPU from going into lower states during idle. The cheapest one I found that others related had ASPM actually working was the Intel X710, and those are much more expensive than the ConnectX-3.
- ApolIllo 3y agoI avoiding older 10gbe NICs due to power consumption. Maybe that's why?
