AMD is working on new SKUs based on its “Polaris 10” silicon, which will be built on a more refined 14 nm FinFET process, which should allow for higher clock speeds and improved efficiency. These SKUs will include the Radeon RX 580 and Radeon RX 570. Reference designed versions of these card have been pictured and reveal some interesting things.
First off these cards are not just strictly “rebrands” of the RX 480 and RX 470. Each will feature higher clocks as well as a redesigned VRM. The Radeon RX 580 draws power from a single 8-pin PCIe power connector, while the RX 570 draws power from a 6-pin PCIe connector.
The RX 580 will be running at about 1340 MHz (vs. 1266 MHz of the RX 480), with its memory speed unchanged at 8.00 GHz (GDDR5-effective), while the RX 570 runs at 1244 MHz (vs. 1206 MHz of the RX 470), with its memory clock slightly increased to 7.00 GHz. AMD has also seemed to have done away with the DVI port on these card.
According to reports both of these cards will be launched on April 18th 2017.
