Yes, both slots need to be x16 electrically. This ensures compatibility and proper functionality.
Need a minimum of eight or more? I believe 3090 should work fine with that amount.
That's one test with one workload. I wouldn't presume without knowing for sure if the build is for a specific purpose. It is quite easy to do a general estimate by observing the bus utilisation in GPU-Z under load and you can extrapolate from there. Can't find details, as it is not something I was that deep into, but I recall folding is notably hindered if you run it x1 mining style. I'm pretty sure some other previous distributed computing GPU projects did have some significant bus utilisation during the PCIe 3.0 era.
Z690 focuses heavily on M.2, which makes it seem like many didn’t prioritize proper electrical connections. It’s disappointing since I’d prefer PCIe slots over multiple M.2 ports. Who would be using so many M.2 drives?
It's mainly due to the high cost of PCIe Gen 5 switches. Gen 4 ones were already costly (hence only half of X570 and B550 boards support x8/x8), and Gen 5 adds more. Z690 boards start around $500 and include x8/x8, while cheaper options lack it because PCIe Gen 5 demands more advanced PCB layers and the Z690 chipset is expensive on its own.
