The US sanctions have resulted in the limited availability of various high-tech products. These include AI accelerators like Nvidia's H100 and A100, and high-end graphics cards, specifically the Geforce RTX 4090. In an adaptive move, Nvidia is reportedly developing a modified version, the Geforce RTX 4090 D, specifically for the Chinese retail market to navigate these restrictions.

AMD's Radeon RX 7900 series, as reported by the Chinese website EXPreview, is also facing a significant rise in demand. Interestingly, despite this increase, the prices for custom variants of the AMD Radeon RX 7900 series have remained relatively stable, indicating a resilient market response expreview reports.

Board Channels [The Geforce RTX 4090] import restrictions have led to increased demand for the Radeon RX 7900 XTX and 7900 XT, resulting in critical GPU supply. Ultimately, AMD faces the challenge of achieving the planned production volume of these two GPUs [Navi 31 XTX and XT].
The problem lies in AMD's inadequate production planning, which will not only result in a severe shortage in Q4 2023, but may extend into Q1 2024, maintaining a state of shortage.

This situation underscores the complex interplay of geopolitical factors and trade limitations in the graphics card market, with AMD's RDNA 3 graphics cards experiencing heightened interest in the Chinese market as a consequence of these global dynamics.
