AMD Radeon RX 570 & RX 580 round-up: Polaris update

10 models of ASUS, Gigabyte, MSI and Sapphire tested


Two flavours RX 580

While AMD did not say anything in the beginning, as it turned out there are actually two variants of the Radeon RX 580. The Polaris 20-chip exists for the RX 580 in an XTX- and an XTR-version. The latter is only found on the (slightly) more expensive models and, as we will find, that chip has more overclocking potential.

The manufacturer does not want to go into detail about the technical differences between the XTX- and XTR-chips. AMD did confirm that they are manufactured using the latest 14nm-procedure of Globalfoundries. As such, there is no physical difference between the two variants.

Seven AMD Radeon RX 580s of four different brands.

We do not know for certain whether or not there are hardware differences or that the distinction is purely made by binning. In this test the ASUS RX 580 Strix Top, Gigabyte RX 580 Aorus XTR, MSI RX 580 Gaming X+ and Sapphire Nitro+ LE are equipped with an XTR-chip. All other cards have a regular XTX Polaris 20 chip.
