You can link two PCIe 3.0 GPUs at X16 speeds if each slot supports them individually.
Absolutely, the eight lanes remain eight, the bandwidth stays consistent, and with a Gen 3 device that has eight lanes, they'll be Gen 3 with eight lanes.
Bandwidth refers to data rate, while lanes represent physical pathways for transmission. Speed cannot simply become more lanes through magic. It's similar to wondering if reducing your car's speed would allow it to split into two separate vehicles.
It seems you're asking if you can divide a $20 bill into smaller bills and use them individually, similar to how a chip manages different PCIe versions. Think of it as breaking down larger denominations for specific uses, just like separating PCIe lanes for various devices.
