ASUS RX 570 Strix OC, RX 580 Strix OC & Strix Top
ASUS sent us three graphics cards for this round-up. For starters they sent us the Strix OC-versions of the Radeon RX 570 and RX 580. The RX 570 Strix OC resembles the Strix-card from the previous generation and uses the exact same cooler as the RX 470. For the RX 580 Strix OC, ASUS used the two and a half slot MaxContact cooler of the GTX 1080 Ti, with six heatpipes and three fans.
Both graphics cards have a few noteworthy features. Of course both have rgb-lighting that you can control via Aura Sync and synchronize with other products. For the RX 570 this is limited to a small ROG-logo on the top, while the RX 580 has coloured leds all around the card. FanConnect makes a return as well, allowing you to control extra casefans according to the GPU-temperature. If you want you can even give them their own profile. On the RX 570 we find a single PWM-header, the RX 580 has two.
The RX 580 Strix Top has the same 30 cm long cooler as the Strix OC, but is based on a Polaris 20 XTR-chip. Most cards have the so-called XTX-variant. The XTR-version is supposed to be better for overclocking, but AMD remains vague about the technical differences between the chips. At least physically there is no difference and according to AMD they are both manufactured by Globalfoundries. In our overclocking test we will find out whether or not they are actually better at overclocking.
