For the time being, what you see above will be the top product stack starting with the Radeon RX 480. The Radeon RX 480 graphics card will be made available in 4 and 8GB versions, you will also spot both reference and tweaked SKUs from the board partners. The GPU used in this puppy is based on Polaris 10 (XT), an Ellismere (codename) GPU based on 4th generation GCN architecture. The 14nm FinFET+ process based Radeon RX 480 will push the product to well over 5 TFLOPS. With its 150W TDP it has 36 CUs (compute units aka shader clusters) x 64 shader processors per CU = 2304 shader processors). The card will be available in both 4GB and 8GB versions and has 256-bit GDDR5 memory which offers an effective 8 Gbps / GHz much like the GeForce GTX 1070. The card will run in the 1267 MHz range on its boost clock. Expect board partner cards to run a good 50 MHz faster. The GPU retains technologies of the Radeon GCN lineup such as DirectX 12, FreeSync and XDMA for CrossFire support. The GPU with its 2304 shader processors are tied towards 32 ROPs with 144 texture memory units. The initial consumer graphics card based on Ellismere (XT model) is the Radeon RX 480, the PRO model will get 32 compute units and thus has 2048 shader processors. The Radeon RX 480 is based on a much smaller 14nm fabrication process, as such you will see many enhancements in efficiency and that shows in power consumption, the reference cards will use just one 6-pin power PEG (PCI Express Graphics) header to give the the card its power. The reference boards have a 6-phase VRM power supply design and display output wise the new cards have seen an upgrade as well, including three DisplayPort 1.4 connectors and one HDMI 2.0b. AIB partners may release SKUs with a DVI connector as well, the reference PCB shows SMT traces for a DVI connector. Overall the specs show a very potent card to play the latest games with whilst offering a good memory size versus price in the 1920x1080 and even 2560x1440 monitor resolutions.
