NVIDIA: "We’re limiting the hash rate of GeForce RTX 3060 GPUs so they’re less desirable to miners and launching NVIDIA CMP for professional mining."
@a1batross @Bobo_PK @fribbledom The mining cards appear to actually be quite bad (they're chips that failed to meet levels for GeForce so lower clocks with higher power demands) - presumably will be sold cheap and by the pallet. https://www.anandtech.com/show/16493/nvidia-launches-cmp-dedicated-mining-hardware
They claim the silicon + BIOS handshakes driver so unlocking/hacking 3060s may take a while (or maybe they did it poorly & a workaround appears on day 1).
@shivoa @a1batross @Bobo_PK @fribbledom The silicon might not be able to reach high frequencies due to several factors, only one of which is higher power, so their claim that the CMP chips will have higher efficiency might be true. In general, for consumer products, the "hot" silicon is given, as the more efficient chips can be delegated to server market where it is a lot more important.
@fribbledom be nice if NVidia detected impending climate doom and the cards bricked themselves upon detecting crypto.
@fribbledom I wouldn't be surprised if Nvidia gets themselves sued over this move. They've advertised certain base specs and capabilities for their products. To then artificially cripple those products because they don't like how those customers are using those products post sale is going to piss people off and there is always a lawyer just waiting to launch a lawsuit against a company with deep pockets.
@lastfuture @fribbledom Sale doesn't just mean to end retail customers though. I wonder if Nvidia was up front about this with their board partners when their board partners were deciding on how many chips to order? Recognize that device manufacturers may be sitting on a heap of chips that now became suddenly less desirable. Maybe that won't effect salability of the end product given how ridiculously distored the PC parts market has been this past year, but I wouldn't bet on it.
@Infoseepage I think it's bold to assume board partners would hear about the halved hash rate and NVIDIA CMP at the same time as the public. They announced partner availability of CMP on their website so they must've been in talks with at least those listed
@fribbledom Oh ja, das passt wieder mal wie Arsch auf Eimer NVIDIA.
Wie sagte das Linus Trovalds damals noch gleich?
In a talk held at Aalto University in Helsinki Finland, Linus Torvalds addressed a question from one of the audience members regarding issues they had with a...
@jlamothe There are chains that use ASIC-resistant hashing algorithms. Ethereum, for example, uses Ethash which was originally billed as needing a block of memory to complete hashes and only sees minimal performance gains when using ASICs or FPGAs. Bitcoin and its forks are all ASIC-able though.
@chip I guess they can make it resistant to the current batch of ASIC chips, but isn't it only a matter of time before new ones come out, isn't it?
@jlamothe True that it still boils down to: is the asset being mined worth fabricating ASICs. Again in the case of Ethereum, part of the ASIC-resistance comes from having to load the chain's entire Directed Acyclic Graph (DAG) into memory to perform the hashing. While GPUs are remaining above the current 4GB size, some of the ASICs are no longer functional as they have <4GB onboard. Similarly as smart-contracts can do any work via the EVM, ASICs have to be general processors vs BTC scrypt ASICs.
In the early days there was the threat of "if you miners fab ASICs, we'll just fork the chain and make your ASICs worthless" but that seems to have died down. Now that Ethereum is moving towards proof of stake it's less attractive. However, miners are naturally long these assets and the underlying paper value has shot up so maybe they do have tons of capital to get some silicon fabbed. F2Pool for example is still trying them.
