AMD plans to launch its Radeon RX 500 Series graphics family, split into two parts by the beginning of April.

On April 4, the Radeon RX 580 and Radeon RX 570 will be on sale, while a week later, on April 11 you will see the launch of Radeon RX 560 and Radeon RX 550. Now come to the bad news, these four graphics cards would be based on Polaris refresh GPU core, in other words, Radeon RX 480, RX 470, RX 460 and RX 450 respectively renamed.

But the good thing is that in May-June we would see the complete line-up of Radeon RX 500 graphics cards using VEGA silicon, under the name of Radeon RX VEGA.

With regard to the Radeon RX 500, the Radeon RX 580 reaches 1340 MHz (+74 MHz compared to the RX 480). The Radeon RX 570 will be 38 MHz faster than the Radeon RX 470, and both will be available with 4GB / 8GB GDDR5 memory.

The Radeon RX 560 could offer 1024 Stream Processors at 1287 MHz (vs. 896 Cores with 97 extra MHz), while the Radeon RX 550 could use a Polaris 12 silicon.
