The RX 480 has been an outstanding addition to AMD’s lineup of GPUs. AMD’s beginning to the financial year has taken a kick-start after the launch of the Polaris powered RX 480 which has taken the market by storm. Lots of RX 480s went out of stock in the US soon after the release of the much anticipated GPU as the card offered a performance / dollar ratio that no other card isn’t even in the proximity of miles. The RX 480 offers stellar performance sitting right between that of a GTX 970 and R9 390 at a meager price of $200 but no success goes without its own share of encumbrances and in this case, it was the PCIe power draw.
RECOMMENDED: NVIDIA GTX 1080 Overview Kingpin?
While the RX 480 isn’t the first card to violate the PCIe specification, this is the first time a fully fledged investigation has been conducted in order to bring it to AMD’s notice. Earlier, the GTX 750 Ti wasn’t in compliance with the PCIe specification as it drew close to 150W on full load. It seems that all the efforts made by the consumers and reviewers have made the issue on the RX 480 quite striking and AMD has promised to release an immediate hotfix that would minimize the power draw from the PCIe port and increase it through the 6 pin PCIe connector that the reference versions of the RX 480 sports. However, the AIB (Aftermarket) variants are soon to be released with additional 8 pin PCIe power connectors and this could well impede the sales of the reference RX 480.

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 8 Gbps 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).
