It's an unconfirmed rumor.

Also I'd be skeptical to some extend on this. Maybe back in time when a chip fail ratio was lower was a case. But now, there is a quite measurable amount of chips not passing requirements for a high tier cards, but can be used in the lower models (with limited amount of cores etc or worse thermal efficiency).

It seems plausible given stuff like this:

"A developer driver inadvertently included code used for internal development which removes the hash rate limiter on RTX 3060 in some configurations," the company said in a statement. "The driver has been removed."[1]

So it's hard to tell when it's binning, and when it's hobbling.

They had to leak it at least once. But seriously, I thought they were clear about this being a driver implementation and not a hardware restriction.

Yeah, they were not clear :)

“It’s not just a driver thing,” said Bryan Del Rizzo, Nvidia’s head of communications, last month. “There is a secure handshake between the driver, the RTX 3060 silicon, and the BIOS (firmware) that prevents removal of the hash rate limiter.”

Signed firmware, probably why they are so reluctant to share those for newer cards for Nouveau… because it’d break their market segmentation.
