AMD Admits Faulty Vapor Chamber Causes RX 7900 XTX Throttling
The Radeon RX 7900 XTX continues to be one of the best graphics cards on the market. Unfortunately, some reference models suffer from overheating. An independent analysis points to a flaw in the vapor chamber and today AMD has publicly admitted that the problem behind the Radeon RX 7900 XTX’s thermal throttling issue is likely the thermal solution.
“We are working to determine the root cause of unexpected throttling that some people have experienced while using their AMD Radeon RX 7900 XTX graphics card. Based on our observations so far, We believe the issue is related to the thermal solution used in the AMD reference design and appears to be present on the limited number of cards sold. We are working on it. Customers experiencing this unexpected throttling please contact us AMD support (opens in new tab)an AMD representative told Tom’s Hardware.
For obvious reasons, AMD did not disclose how many MBA (made by AMD) units are affected. “Limited number” is a vague term and could mean anything from a bad batch to a few batches. On the bright side, the thermal solution does not affect all reference Radeon RX 7900 XTX graphics cards, only certain batches of unlucky cards.The custom design uses AMD’s reference cooling solution. This is not a problem because it is not Additionally, AMD has confirmed that this flaw only affects the Radeon RX 7900 XTX, so the Radeon RX 7900 XT is not affected.
In AMD’s defense, the chip maker does not manufacture thermal solutions for the Radeon RX 7900 XTX. This is probably due to AMD’s suppliers’ poor quality control of the final product. However, it seems odd that the entire batch or batch was defective. After all, it’s an AMD product, so the company is responsible for its functionality, whether it’s an accident on the manufacturer’s part or not.
The key now is for AMD to work with suppliers to narrow down affected batches and issue recalls. Luckily for AMD, only a “limited number” of Radeon RX 7900 XTX graphics cards show poor cooling, leaving the chipmaker to lose some money in the fiasco, but that’s what the world’s It doesn’t seem like the end.
