‘As you know, we continuously tune our GPUs in order to maximize their performance within their given power envelopes and the speed of the memory interface, which in this case is an unprecedented 8Gbps for GDDR5. Recently, we identified select scenarios where the tuning of some RX 480 boards was not optimal. Fortunately, we can adjust the GPU’s tuning via software in order to resolve this issue. We are already testing a driver that implements a fix, and we will provide an update to the community on our progress on Tuesday (July 5, 2016).’
The statement above came from AMD after a number of reviewers who found out that the newly launched RX 480 is drawing more power over the PCIe than the supposed PCIe standard. Which means, you’re an inch away from getting your motherboard fried.
While it has been confirmed that the fix will come in the form of a driver, AMD hasn’t disclose any details on what the driver actually does. It could be a fix that limits the power target of the RX 480 to prevent further power draw that goes above the PCIe starndard. If this does happens, existing benchmark result of the RX 480 review that we’ve seen on the net will no longer be valid as those are the extra numbers on the scores and FPS result of the card over drawing power from the PCIe slot and reviewers might have to revisit the review to get the numbers right.
