This is the kind of card people ask about all the time: a 10GBase-T NIC that’s only PCIe Gen4 x1. I brought it into the discussion because it’s a perfect example of why you must understand PCIe bandwidth and then validate with iPerf3 instead of assuming “10GbE” guarantees 10Gb throughput.

Pros
- +PCIe 4.0 x1 design targets newer motherboards with higher per-lane bandwidth
- +10GBase-T RJ45 is convenient if you’re already running copper
- +Good fit for compact builds where x4 slots are limited
Cons
- -Older PCIe generations can bottleneck a x1 10GbE card
- -10GBase-T typically runs hotter than SFP+ solutions
