AMD launched its first Polaris GPU, the Polaris 10 based Radeon RX 480, all the way back in 2016 and it looks like they still aren't finished with Polaris based GPUs. A recent report from Expreview (via Videocardz) reveals that AMD's board partners are introducing a new graphics card based on the Polaris GPU architecture known as the Radeon RX 590 GME.

As per the report, Chinese retail outlets such as JD.com has listed several new Radeon RX 590 GME graphics cards. The graphics cards aren't a specific model by a specific AIB but rather, multiple AIBs have released their own custom Radeon RX 590 GME graphics cards. Currently, there are four AIBs who have gone public with their models which include Sapphire, PowerColor, XFX, and ASRock.
