AMD Radeon RX 590 GME is a Polaris 20 XTX for the Chinese market

AMD is bringing back Polaris for yet another spin. VideoCardz noticed new Radeon RX 590 GME video cards are making it to the market. This appears to be a China-exclusive model based on the old 14nm Polaris 20 XTX GPU. Basically, it's a rebranded Radeon RX 580, with performance about 5 percent lower than the regular Radeon RX 590. There are no official clockspeeds but the slowest Radeon RX 590 GME is the PowerColor Red Dragon, which offers a 1380MHz Boot (for comparison, the non-GME version has a 1555MHz Boost).

The Radeon RX 590 GME features Polaris 20 XTX GPU, not Polaris 30 as the original RX 590. This is without a doubt a continuation of misleading product naming by AMD and this is likely why we won’t see this model on different markets. AMD’s Polaris 20 is a 14nm processor, while Polaris 30 is 12nm. The latter offers more headroom for higher clocks and there is no logical reason to call the new model an RX 590. Yet, here we are.
