NVIDIA prepping more GPU revisions with hash rate limiter?

Yesterday news hit the wire about a new GA106-306 GPU revision from NVIDIA. This chip would allegedly introduce a new and more advanced hash rate limiter to make the GeForce RTX 3060 less attractive to cryptocurrency miners. NVIDIA tries to make this model less attractive for mining purposes by implementing an algorithm that roughly cuts the performance in half when it detects Ethereum mining. Unfortunately, NVIDIA accidentally released driver code that bypassed the hash rate limiter, resulting in the need for a new chip revision.

Now word is going around that other NVIDIA Ampere GPUs may get a revision too. Well-informed Twitter leaker kopite7kimi claims NVIDIA may also be working on new variants of the GA104 and G102. Basically, if this is true, this means a hash rate limiter is on the way for the GeForce RTX 3070, RTX 3080, and RTX 3090 lineups.

Rumors about these revisions have been circulating since February so it will be interesting to see if NVIDIA is indeed doubling down on its anti-mining effort for the GeForce cards. In the meantime, the company is pushing CMPs for miners and that effort is turning out to be more succesful than the green team expected.

I've said before, maybe not GA106 only.
For example, we would meet GA102-302/202 and GA104-302/202. https://t.co/pGghHbikbV
