We know AMD is preparing to launch new Radeon SKUs based on its “Polaris 10” silicon built on a more refined 14 nm FinFET process, to offer higher GPU clock speeds, and improved energy efficiency over previous models. Now pictures of the Radeon RX 580 and the Radeon RX 570 reference-design has spotted, and aren’t strictly “rebadged” RX 480 and RX 470. The two feature higher clocks, and with much better redesigned VRM. The RX 570 draws power from a single 6-pin PCIe power connector, while the RX 580 draws it from a single 8-pin connector.
Though, the GPU core-configurations of the RX 580 and RX 570 aren’t different from their predecessors RX 480 and RX 470. The RX 580 still features 2,304 stream processors, and the RX 570 features 2,048, but clock speeds are increased this time. The RX 580 features a 1340 MHz clock speed (vs. 1266 MHz of the RX 480), with its memory speed still remain at 8.00 GHz (GDDR5-effective), while the RX 570 is clocked at 1244 MHz (vs. 1206 MHz of the RX 470), with a higher memory clock of 7.00 GHz.
One thing is interacting to see on the pictures that reference-design of both cards ditch the DVI port (just like NVIDIA did with GTX 1080 Ti). The new cards are expected to launch on the 18th of April, 2017.
