NVIDIA's RTX 5090D graphics card, tailored for the Chinese market, has introduced an array of stringent restrictions in addition to curtailing Tensor AI computing power. Notably, the card is designed to automatically lock its hash rate in AI and mining-related applications. If the GPU engages in such tasks for more than three seconds, it will instantly limit the hash rate by reducing frequency or implementing software-based performance constraints. Furthermore, the RTX 5090D has eliminated support for multi-GPU interconnection, and its power consumption settings are tightly regulated. These measures are intended to deter the misuse of graphics cards for unauthorized purposes, thereby safeguarding hardware integrity and mitigating excessive energy consumption. Despite these limitations on AI computing capabilities, the RTX 5090D is expected to have minimal impact on gaming performance, potentially fulfilling the needs of everyday gamers.
