No real answer
Usually people say that it shouldn't. It should affect only eth.

But shouldn't doesn't = it is not affecting
We have not seen any indication of LHR affecting speed in hashcat. Many people are running LHR cards with hashcat and none have reported issues that were confirmed to be LHR related. So far, looks like it's been fine.
