From the web of Benchlife we have leaked specifications that would correspond to the launching of the new series of graphics cards AMD Radeon RX 500.
AMD Radeon RX 500 leaks confirm that new graphics will have a rehash of the current 400 AMD series but with the most optimized Polaris cores and back up. Also with the exception of the new Polaris 22 core that is the first appearance on the scene.
The first thing to know about this new series Radeon RX 500 is that will be manufactured with the special manufacturing node of 14 nm FinFET LPP (Low Power Plus). While in front of the current series RX 400 that is manufactured with the node with 14 nm FinFET LPE (Low Power Early) in AMD Radeon RX 500.
The difference between both nodes is that the latter is the one used as a platform for launching a chip and the second is used when the process is already mature and incorporates some improvements in both consumption and performance for AMD Radeon RX 500.

Another thing we know is that AMD Radeon will reuse the current Polaris cores 10 and 11 for their graphs. While differentiating these from the current Polaris changing to the denomination series 10 to the series 20.
That is to say, if we now have a core Polaris 10. We will have a Polaris 20 core with the RX 500. The truth is that this reuse of the current refined Polaris cores is something that will surprise anyone at this point, so we will have cores as:
- Polaris 20 XTX: will be installed on the next Radeon RX 580. Maintaining the 2,034 Stream Processors, 144 TMUs and 32 ROPs. Its performance should be higher than the current RX 480. Although I doubt there is not too large difference.
- Polaris 20 XL: Will be installed on the next Radeon RX 570. Maintaining the 2,048 Stream Processors, 128 TMUs and 32 ROPs. Its performance will be higher than the current RX 470, although I doubt it is really very much higher.
- Polaris 21: Will be installed on the next Radeon RX 560. And, unlike the old RX 460, will have all 1024 Stream Processors unlocked. Its performance would be superior to that of the current Radeon RX 460.
- Polaris 22: Will be installed on the new Radeon RX 550. And will use the old original Polaris 11 core with only 896 Stream Processors. So its final performance should end up being quite similar to this graphics card.
In short, I am convinced that card manufacturers will reuse existing PCBs. That they have from their models to bring the new models AMD Radeon RX 500 to market.
