The Chinese-designed RTX 5090D features AI and cryptocurrency mining caps, and multi-GPU configuration is also locked
Next Nvidia focus on China RTX 5090D It is claimed to be locked, preventing users from using Blackwell GPU for specific workloads. User on Chevelle Forums Reports indicate that after “3 seconds,” the RTX 5090D locks itself, preventing users from running certain workloads, overclocking the GPU, adjusting power threshold parameters, and even using the GPU in multi-GPU setups.
The “D-series” RTX (for Dragon) is a dedicated Nvidia GPU designed specifically to meet your needs. US export regulations Based on GPU performance. previous generation RTX 4090 It was too strong to be exported to China legally. Hence, Nvidia had to roll out rtx 4090d, Slightly less potent than its vanilla counterpart, to meet regulations. The RTX 5090D is the successor to the RTX 4090D.
Nvidia had to repeat the same strategy with the RTX 5090, but for the RTX 5090D variant, it changed how it implemented that strategy. The previous generation RTX 4090D featured a material drop in GPU specs compared to the vanilla RTX 4090, running 12.8% fewer CUDA cores, 5.9% less power (maximum power), and slightly different core clock speeds. the RTX 5090D He turns things around and includes Full Vanilla RTX 5090 specs, right down to the base and boost clocks. The only thing Nvidia changed was the RTX 5090D’s AI performance, which was “magically” reduced by a whopping 29%.
We say magically because it remains a mystery how Nvidia hampers the RTX 5090D’s AI performance. Performance drops from 3,352 AI TOPS to 2,375 AI TOPS.
Chiphell’s user discovery reveals that Nvidia relies heavily on driver and/or synthetic firmware limitations to keep the RTX 5090D’s performance in check. For example, the driver appears to halt the RTX 5090D’s performance by a maximum of three seconds when it detects an AI inference or cryptocurrency mining workload. Obviously, generative AI was not affected.
The RTX 5090D appears to have a non-adjustable power limit, preventing potential user exploitation. Therefore, you cannot overclock. In comparison, the RTX 4090D’s power limit is not restricted, so users can open it up to 600W and overclock to regain lost performance.
User Chiphell was upfront that the RTX 5090D cannot be modified or processed online (or from the cloud) and cannot be run in a multi-GPU setup. Nvidia has allegedly locked this functionality down to “the bottom layer of Linux.” The user neglected to share how the RTX 5090D behaves when another GPU is installed. However, regardless, it looks like the RTX 5090D won’t be able to run any workloads in unison with another GPU, to say the least.
Only time will tell if Nvidia’s selectors will work or not. to remember LHR (simple hash rate) Catastrophic failure during major GPU shortage? The limiter was supposed to limit the mining performance of the RTX 30-series GPU to prevent crypto miners from gobbling up all the shares. It did not take long for individuals and organizations to find an alternative solution.
