There is definitely a lot to choose from if you are looking for a new AMD-card. In this round-up of AMD Radeon RX 570- and RX 580-graphics cards we see a few models that stand out in a positive way.
To start off with the three affordable options: the RX 570s of ASUS, Gigabyte and MSI. In terms of performance in games there is next to no difference and the difference in the throttling test is negligible. However, the ASUS Strix OC clearly has higher noise levels than the other two and is also more expensive. A shame, because if we look at the cooling efficiency that card could have easily been just as quiet. Of the two that remain the MSI has a slightly better cooler and the Gigabyte is slightly cheaper, but in our opinion they are both excellent choices and therefore worthy of an Excellent Choice-award.
The two cheapest RX 580s in our test are manufactured by MSI and Sapphire. The Sapphire-card is not the quietest, but does have exceptional overclocking abilities for its 'regular' XTX-chip and performs pretty well. If you are looking for an affordable RX 580, the Nitro+ is an attractive choice. While the Gaming X-edition is usually very good, it does not convince us this time. It is loud, throttles under load and does not offer much in terms of overclocking.
Nevertheless there is an Excellent Choice-award for MSI, because the Gaming X+ is only slightly more expensive than the regular version and has a better performing cooler. It is also the cheapest RX 580 with an XTR-chip. Furthermore it is the quietest of all of them. The Gaming X+ is basically what the Gaming X should have been and an excellent choice.
The Sapphire RX 580 Nitro+ Limited Edition is the fastest card out-of-the-box and also shows the most potential when overclocking, but for its relatively high price we expected a better cooler. Lastly, the most expensive participant is the ASUS RX 580 Strix Top. The agressive fan profile and corresponding noise levels are slightly less than top as the name suggests. As with the RX 570, ASUS should definitely look at the tuning of the card.
