AMD Radeon RX 590 GME features Polaris 20 XTX

At the Financial Analyst Day, AMD executives were proud of the fact that their production has now shifted to 7nm for both Ryzen and Radeon. However, it appears that not only 12nm but also 14nm products are still being released, with Radeon RX 590 GME being one of such ‘zombie rebrands’.

 AMD resurrects Polaris 20

The Radeon RX 590 GME is an exclusive model for the Chinese market. Only four cards have been revealed by the board partners and can be found through Asian e-tailers. At Expreview you will find the very first review of the RX 590 GME from XFX. This model is actually the fastest GME model out of the four (with a boost clock of 1460 MHz).

There are no official clock speeds for the RX 590 GME, but the slowest model is PowerColor’s Red Dragon with a 1380 MHz boost (the non-GME model features 1555 MHz clock). This a significant decrease in the frequency and it appears to be associated with the GPU.

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.

In fact, the RX 590 GME is around 5% slower than non-GME. In terms of overclocking, the reviewer at Expreview basically gave up, because even an 80 MHz uplift resulted in issues. In other words, the RX 590 GME is basically a rebranded and overlocked RX 580.

The conclusion of the review is straightforward: Radeon RX 5500 XT is a much better product, although it costs 1399 Yuans, while the RX 590 GME retails at 1199. Not to mention, the Navi 14-based model offers more OC headroom and consumes less power.
