AMD’s launch of the Radeon RX 480 didn’t go too smooth with lots of complaints about power issues with the card. Many sites have reported the card was drawing too much from the PCI-express slot which is above the allowed 75W consumption. Over the weekend, AMD has released a statement regarding the issue and looking to implement a fix via driver and provide an update tomorrow (or Wednesday our time)
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).
On the bright side, the Radeon RX 480 has been reviewed really well with its best price per performance coming in at a cheap entry price point for VR consumers.
