Recently announced that Nvidia would be limiting the mining efficiency of their Nvidia RTX card range. The mining efficiency would be reduced by as much as 50% through software. However, this software limitation has been circumvented by a number of Chinese cryptocurrency miners within two weeks.
Measures from Nvidia to reduce pressure on graphics cards
This restriction was initially imposed because there has been a huge stock shortage for a long time. This is because of the global corona measures that make the production and distribution of graphics cards difficult. Many of the graphics cards still available are bought by bots from cryptocurrency miners and scalpers. Scalpers are individuals or companies who buy up stocks of hard-to-obtain products and then sell them for a higher price. The regular gamers also try to get hold of one of the new graphics cards. This creates a very difficult situation.
However, to partially solve this, Nvidia has come up with a solution: limiting the hash rate when performing cryptocurrency-related activities. This by developing software and implementing it in the graphics cards. In addition, Nvidia also comes with a product specially developed for cryptocurrency, which should reduce the pressure on their regular graphics cards. However, it now turns out that Nvidia’s software can be bypassed relatively easily. This while Nvidia has previously indicated that end users would not be able to extract the hash limiter from the driver in any way. This now turns out to be untrue.
The software has been developed so that it can analyze what tasks are being performed. In this way, it can be checked whether cryptocurrency-related tasks have been performed or not. If it did, the hash rate would be reduced by 50%. An example: The new Nvidia GeForce RTX 3060 can normally output about 45 MH per second. This equates to about 45,000,000 hashes per second. When crypto-related tasks are subsequently recognized, this falls to around 20–22.5 MH per second, a significant decrease in the efficiency of the card.
Chinese groups, along with Vietnam modders, managed to circumvent those restrictions. This is not a positive sign for the global gaming community. This could possibly ensure that the stock shortages are far from being resolved. However, the upcoming product specially developed for cryptocurrency could provide some relief.
