AMD's Radeon RX 500 series will reportedly launch in the beginning of April, RX Vega series to debut between May 30th and June 3nd.
AMD's RX 500 Series Refresh - Polaris Based RX 580, 570, 560 & 550
The first of the Raden RX 500 series refresh will include the RX 580 and RX 570. Both cards will reportedly feature higher clocked versions of AMD's Polaris 10 XT and Polaris 10 GPUs which currently power the RX 480 and RX 470 graphics cards. The RX 580 and RX 570 are said to deliver roughly ~10% better performance than their predecessors. These GPUs are said to be coming on April 4th.
The lineup is reported to also consist of the RX 560 and RX 550 which will come a week later on the 11th of April. These cards will be based on the smaller Polaris 11 silicon found in AMD's RX 460. Again a small performance improvement is expected thanks to higher clock speeds.
AMD's Brand New RX Vega Series - Vega 10 & Vega 11
The Radeon RX Vega series includes two brand new GPUs called Vega 10 and Vega 11.
It's still not known what type of numbering scheme AMD will employ for this class of RX Vega graphics cards. What we do know is that Vega 10 is the high end iteration of the Vega architecture. This chip will be the flagship of AMD's new product stack and is set to compete with NVIDIA at the high-end. An early engineering sample of this GPU has already been demonstrated in action, outperforming the GTX 1080 by approximately 10%.
We've already heard reports that 80% of AMD's current driver team is working on optimizing and fine tuning the drivers for Vega. So the final silicon may end up measurably faster than what we've already seen. A full Vega 10 features 64 next generation compute units each housing 64 stream processors, for a total of 4096 GCN stream processors. The chip has a 2048-bit memory interface and graphics cards powered by Vega 10 will feature up to 8GB of 2nd generation High Bandwidth Memory.
Vega 11, the smaller chip of the two is said to be AMD's new high performance mid-range contender. A GPU that's expected to fit into AMD's future product stack where the 1070 current sits in NVIDIA's. Whether this GPU will actually be on par, outperform or underperform the GTX 1070 is still unknown. This GPU hasn't been part of any public showcase or demonstration to date.
