Radeon RX 570
This board once again comes with a 6-pin power connector and your three DP and one HDMI connectors. This reference design again misses a DVI port. If the photos are for real then it confirms that Radeon RX 570 is using Polaris GPUs.
AMD Radeon RX 580

The label shows again, Polaris being fabbed March 3rd. For the specifications, a GPU-Z screenshot was also posted and it seems that the specs for RX 570 are 2048 Stream Processors, 128 TMUs and 32 ROPs. That's similar towards the Radeon RX 470s. If the screenshot is for real, the AMD has not increased the memory speed on new Polaris SKUs. The RX 570 4GB will have 4GB and 8GB GDDR5 memory configurations at 7 GHz effective frequency.
