Chinese users of expensive Nvidia graphics card models, especially the GeForce RTX 4090, cannot have their devices repaired under warranty in case of a serious malfunction. In such cases, service centers send broken video cards from leading vendors (Nvidia, Asus, MSI, Gigabyte and others) to Taiwan, but since deliveries are prohibited due to sanctions, it is no longer possible to get the card back.
The device owner then receives the money, but the question remains whether the user can buy a new device for the same price. In practice no.
