Because HN doesn't provide link previews, I'd recommend adding some information about the content to your comment. Otherwise we have to click through to YouTube for the comment to make any sense.

That said, the video is the GamersNexus one where they talk about an unverified claim that this is a fabrication process issue caused by oxidation between atomic deposition layers. If that's the case, then yeah, microcode can only do so much. But like Steve says in the video, the oxidation theory has yet to be proven and they're just reporting what they have so far ahead of the Zen 5 reviews coming soon.

GN mentioned shipping a few samples to a lab (number dependent on the price quote from said lab), so I hope we’ll have some closure regarding this hypothesis.

Hopefully Intel ships them, and allows them to, test and publish benchmarks with the current pre-release microcode revision for review comparison.
