I see that Nvidia is going to nerf the performance of the 3060 if it is running algorithms for cryptocurrency, and that they are developing a Cryptocurrency Mining Processor (CMP) to be released later this year.

Just curious if anyone with more knowledge than me knows if the 3060 is going to be crippled in BOINC (I'm guessing no, but maybe?). Also curious if these CMPs would be good for crunching BOINC as well.

I thought I recall someone on the SETI message boards had a contact at NVidia when there was a driver problem. Perhaps they can contact that same person to get a better understanding of the situation? I'm mentioning it so the community could get ahead of a problem before it manifests with other 3060 users.

There have been reports that the 3000 series GPUs will also run slower on Folding@home, which uses OpenCL or CUDA (like most GPU projects on Boinc).
It may be because of the capacitors on the back of some model GPUs.
They've done similar things on the 2000 series GPUs.
All you needed to do was overclock the GPU higher.
Just be sure that the GPU doesn't produce errors.
Newer GPUs will most likely have this issue fixed.

As far as Bitcoin, in order to successfully mine these days, you'll need a 3090 or greater, as they'll more and more need DPP (64 bit).
All lower GPUs have trouble finding hashes, and no longer are cost effective. (the 2060 to 3070 may be for a while still, but bitcoin has reached levels where these GPUs won't be very viable (profitable) anymore reaching closer to the end of the year).
I'd be interested to hear if those bitcoin mining processors would work for folding.

Nvidia's own information claims to specifically target the Ethereum hashing algorithm, which is pretty unique making it easily identifiable for the card. There's no reason at this time to expect impacts to other workloads. If you're not mining ETH, you should be fine.

what in the world are you talking about? lol.

1. the "capacitors" have absolutely nothing to do with this. what you're referring to is a driver level memory clock limitation on Geforce (consumer grade) GPUs. when the GPU detects a compute load it will not allow clocks to exceed the P2 state. when it detects a 3D application it will allow going all the way to P0 state. for Turing (2000 series) the only difference between P2 state and P0 state was that P0 had 400MHz higher memory clock speeds. you can account for this in compute loads by just applying a +400MHz mem overclock. new GPUs still have this limitation (i have a 3070, and have tested it)

2. no one, absolutely no one, is mining Bitcoin with GPUs, and it hasnt been that way since at least 2012/2013. they simply aren't fast enough anymore. even if you took a RTX3090 back in time to 2013, it still wouldn't be fast enough to compete. Bitcoin mining is done exclusively on ASIC machines. Application Specific Integrated Circuit. machines that are thousands of times faster than a GPU at Bitcoin hashing. the hashing speed of these devices is on the order of TERA-hashes per second for the bitcoin algo.

GPUs these days are used for mining altcoins, primarily Ethereum, which uses a memory based algorithm that makes it difficult for an ASIC device to compete due to the need for lots of expensive memory. Some ASICs do exist for ETH still though, just most people use GPUs.
