These are very bad for hashcat, I would strongly recommend AGAINST using risers and splitters such as these as they will significantly impact both performance and stability.

This is in benchmark mode, which uses bruteforce/mask mode where the bus width and speed doesn't have almost any impact. In straight/wordlist, you will see speed/stability issues as the bus will be completely saturated trying to move candidates to the GPU from the host and the GPU will not be fully utilized at all.
