Network cards and on-board solutions differ in how they connect and manage network functions within a device.

I never really thought about this until I looked into it. Do PCI-E network cards perform better than onboard options? I've heard they might, but it really depends on the internet type or router you're using. Installing one could improve gaming performance or just speed up downloads and uploads. I have a speed test photo that shows results matching what my ISP advertises. My current plan offers 200 download, 10 upload, and 900 GB data, but the picture suggests more. Real-world speeds won't match these numbers, so it still makes me question whether a network card is worth it soon. If it could help, which ones would you suggest?
The onboard network chips link to the chipset via a PCI-E X1 lane. These lanes offer a maximum speed of either 500 MB/s (~4gbps) for PCI-E v2.0 or 970 MB/s (~8gbps), meaning you're not restricted by whether the chip is in a slot or onboard. They match the same chips found in PCI-E cards. Motherboard makers often choose more affordable chips, which explains why you see brands like Realtek 8111 and similar models everywhere. At lower price points (around $40 or less), you'll find chips of similar performance levels. For premium options (over $40), you typically get chips with better manufacturing processes or more advanced features, but this usually doesn't increase the transfer rate significantly. Higher-end cards may use slightly less processor power when handling multiple connections—such as downloading from 50 to 100 peers simultaneously at speeds like 3–400MBps—because they manage many streams efficiently.
