Photo's of a Sapphire Radeon RX 480 (AMD reference model) appeared online, the product has been taken apart into the smallest detail.
On the photos below you can see the PCB, VRM area, cooler and actual GPU. The card features a 6-phase VRM area and is fitted with a 6-pin power connector, the photos are courtesy of PCOnline.com.cn.
The product is Polaris 10, based on the Ellismere architecture. The 14 nm FinFET+ process based Radeon RX 480 will perform above 5 TFLOPS. With it's 150 TDP it'll have 36 CUs x 64 shader processors per CU = 2304 Shader processors). The card will be available in both 4GB and 8GB versions and has 256-bit GDR5 memory at 256 GB/s (= 8 Gbps effective much like the GeForce GTX 1070). The card will run in the 1267 MHz range on it's boost clock.

Judging from the photo the reference PCB and this GPU and memory are powered with a single 6-pin PCIe power connector. You can see a 6-phase VRM power supply design. Monitor display outputs include three DisplayPort 1.4 and one HDMI 2.0a connectors. As you can see there are also traces on the PCB for a DVI connector, AIB custom-design cards should implement it.
The Radeon RX 480 is expected to launch on the 29th of June, 2016 for $199 for the 4 GB variant and a (though unconfirmed) an $229 for the 8 GB model.
