AMD Radeon RX 500 Series Now Official

AMD today unveiled its new Radeon RX 500 series graphics card family based on “refined and evolved” Polaris graphics processors. The lineup comprises of the Radeon RX 580, Radeon RX 570, Radeon RX 560, and the entry-level Radeon RX 550.

The Radeon RX 580 and RX 570 are based on the Polaris 20 GPU, while the Radeon RX 560 is based on Polaris 21. Entry-level Radeon RX 550 is based on Polaris 12. All the cards will be available at roughly the same price points as their Radeon RX 400 predecessors, but with improved performance. The performance boost has mainly been achieved by raising the clock speeds, which has made a negative impact on efficiency.

The Radeon RX 580 features 2304 stream processors, 144 TMUs, and 32 ROPs. It features a 1340 MHz boost clock and comes in 4GB and 8GB GDDR5 versions. The reference card draws power from a single 8-pin power connector and has a TDP rating of 185W. AMD claims the card is more than capable of delivering 60+ fps in most games at 1440p resolution, making it a great alternative to NVIDIA’s GeForce GTX 1060 6GB.

The Radeon RX 570 comes with 2048 stream processors and up to 8GB of GDDR5 memory on a 256-bit bus interface. With a boost clock of 1244 MHz, it delivers a total compute output of 5.1 TFLOPs +. With a lower TDP of 150W, the card draws power through a single 6-pin auxiliary power connector.

Based on the Polaris 21 (renamed Polaris 11), the Radeon RX 560 is aimed at casual gamers using a 1080p monitor. The card features 1024 stream processors, 64 TMUs, and 16 ROPs. Consumers will be able to choose between 2GB and 4GB versions, both featuring a 7 GHz memory clock.

Finally we have the Radeon RX 550 with just 512 stream processors, 32 TMUs and 16 ROPs. Similar to the Radeon RX 550, the RX 550 too will be offered in 2GB and 4GB variants.
