After being reported that Nvidia intends to fight against the use of its GPU for cryptocurrency mining using A.I and forcing miners to shift to NVIDIA CMP (Cryptocurrency Mining Processor). New information about the working of the A.I has come out.
According to preliminary reviews, the NVIDIA GeForce RTX 3060 GPU which has not yet been officially launched, even with existing driver versions loses about half of the computing power in mining in 1-2 minutes after the miner is launched. If at first, the device demonstrates a hash rate of about 41.5 MH / s, then after a few minutes it drops to the level of 24-26 MH / s and is no longer restored to its original value – until the next launch of the miner.
This limitation only works when mining Ethereum, but not for other cryptocurrencies. This behavior of the video card may indicate that the protection against mining is not built into the drivers, but into the BIOS of the device itself. By the way, this particular instance of the ZOTAC RTX 3060 Twin Edge was purchased before the official announcement for about $ 830, and the seller has already sold out the entire first batch of GeForce RTX 3060.
However, soon after the announcement of anti-mining protection more information about the implementation of the algorithm has started to come out. First, this technology will not only work on the Windows operating system. According to the available information, the anti-crypto mining technology works like a secure handshake between the driver, GPU chip and BIOS. This clarification from NVIDIA spokesman Brian Del Rizzo explains the behaviour of the ZOTAC RTX 3060 Twin Edge graphics card in the test described above.
Additionally, it is reported that this technology will not be limited to the GeForce RTX 3060 model, but will appear in other NVIDIA video cards. According to the available information, the company intends to restart the existing video cards under the new device IDs. This means that future GeForce RTX 3090/3080/3070 / 3060Ti models will have a different ID and built-in anti-crypto mining algorithm. But previously released video cards should retain the existing mining capabilities. It has not yet been announced when NVIDIA intends to officially announce these changes.
