AMD's Polaris 20 seems to have received a second wind with MSI preparing a new variant of the Radeon RX 580 Armor. This is most likely an attempt to clear out stock of remaining Polaris GPUs in favor of upcoming Navi GPUs.

The new Radeon RX 580 Armor is a redesigned version of existing Polaris graphics cards by MSI such as the original MSI Radeon RX 580 Armor and MSI Radeon RX 580 Armor MK2. MSI has deviated from the initial white and black color scheme to an all-black fan shroud.
