What is the difference between PCIe Gen 3 and PCIe Gen 4?

Sometimes, locking the gpu on cpie lane causes some pins to lose connection You can see the pcie pins being pushed when inserting the gpu

But I intend to use 2 pcie 3 slot : One for graphic card and another for whatever, but not graphic Most of the 1150 socket has two pcie slot,

extra slot ray Hello, we need to connect another device through the pcie x16 slot of AGX Orin, and the other device can start normally only after AGX Orin
