PCI lane speed for fast GPUs - Siegfried1986 - 05-09-2024

Does the PCIe lane speed affect hashrate for wordlist attack? I mean 1x 4x 16x  for 3090\4090 gpu
I suppose the do no matter for mask attack , as all the job is done on GPU, but how it affects large wordlist attack?

Yes. You will see noticeable degradation of speed below x4 usually, so that's probably as low as I would go.
