What is the difference in connecting a capture card by cpu or chipset? why connecting via chipset is not recommended?

PCIe lanes all ultimately go to the CPU. Your motherboard has certain features that need to connect to PCIe lanes but it doesn't always need a full set (like say 4 of them).

To not waste lanes the motherboard manufacturer will use 4 lanes to connect the chipset, connect things like the LAN port and maybe the onboard audio, and then pass the remaining bandwidth to a PCIe port (4 lanes). Even though you have "4 lanes" it's not getting the full bandwidth and lowest latency possible compared to that capture card connecting directly to the CPU.

newer boards like Z790 have more lanes and bandwith to the cpu, via the chipset. But your best bet is allways direct to cpu. you can do thunderbolt, but thats running through the chipset on most boards anyways. i have a Z590 and running via thunderbolt a Avermedia Live Gamer Bolt, it works fine. USB Capture devices are going to go through the chipset, unless you add in a usb card, that goes to the cpu via the pcie lanes, but some pcie lanes goto the chipset, all matters on the board you buy, The most exspensive, gives you the most versatility.
