Hartung believed that the RX 7900 XTX suffered from a defective vapour chamber and that AMD would have to do a general recall of the chip.

However, AMD said that it is not that simple, and it was still trying to determine the root cause of the unexpected throttling experienced by some while using the AMD Radeon RX 7900 XTX graphics cards made by AMD.

“Based on our observations, we believe the issue relates to the thermal solution used in the AMD reference design and appears to be present in a limited number of the cards sold. We are committed to solving this issue for impacted cards,” AMD tells us.

For this reason, it wants RX 7900 XTX customers experiencing unexpected throttling should contact AMD Support.
