There was a test running Tomb Raider where the averages were unaffected but the minimums took a huge dive. I didn't show the results here though because in my experience, the minimums result in the Tomb Raider benchmark is highly irregular. You can follow the link if you want to see them though.That's....hugely concerning. And that's with coffee lake which was supposed to be the least impacted. No mention of gaming benchmarks?
Still, best to wait until the "respected" websites and youtubers do their benchmarks.
