Tech media Videocardz says that the special specification model "RTX 5090D" for China has multiple functional limitations.I am reporting。
It seems to be designed for pure gamers, including performance limiters for AI and mining, and disabling of multiple GPUs.
There are many functional limitations on models for China. Could this be due to the US semiconductor regulations that have been intensifying in recent years?
NVIDIA's latest GPU "RTX 5090D" is a special specification model for China of the regular model "RTX 5090", and although its performance is almost the same as the regular version, there are rumors that there are some functional limitations. However, the details have now been revealed.
According to the article, AI TOPS, which indicates AI-related performance, is suppressed to 2375 AI TOPS in the Chinese specification, compared to 3352 AI TOPS in the regular model, and is activated 3 seconds after detecting AI or mining operation to improve performance. There is a limiter that limits it. In addition, there are various other functional restrictions such as disabling multi-GPU and fixed power consumption settings, and it seems to be a specification aimed at pure gamers.
In recent years, the United States has implemented various regulations in response to intensifying AI development competition with China, and in October 2023, the U.S. Department of Commerce's Bureau of Industry and Security announced that it willSet export controlsIn addition to introducing a certification system focusing on high-performance models in countries such as China, Saudi Arabia, and the United Arab Emirates, in December last year, the system was expanded to include equipment and software essential for chip manufacturing.strengthen regulations。
On January 13th of this year, access to certain AI models from non-US-designated allies was introduced under a licensing system, and regulations regarding AI development are being tightened both in terms of both hardware and software.
In addition, some of the functional limitations reported this time have been implemented for some time, such as the implementation of Lite Hash Rate (LHR), which limits mining performance through software to ease demand as mining demand expands around 2021. Some exist. However, due to changes in Ethereum specifications, LHR will target all models with the 522.25 driver released on October 12, 2022.has been disabled, the reason why it was implemented again this time is unknown.
We will continue to pay attention to future trends, including reports of functional limitations that are thought to be related to the intensifying competition in AI-related technology between the US and China, and the impact on functionality and prices of other models distributed in Japan. That's what I want to do.
