Powercolor RX 5700 XT Red Devil in review – Force is mass times acceleration

Powercolor sets a decent fragrance brand with the RX 5700 XT Red Devil - both in terms of performance and the massive cooler as well as in terms of price. There is also a Silent BIOS that really honors its name. But I don't want to spoil, I want to test. So it's best to read for yourself.

How are you most likely to annoy your competitors? By impressively showing who has the longest and greatest. And if you then stay a little more subdued in terms of price and can score with features, then a product sells almost by itself. Too much praise in advance? Honor to whom honor is due, but you are right. That will be included in the summary later. Now, as always, the focus is on testing the product.

In order to make the whole thing a little clearer and also to get a little more to the point, I have largely retained the structure of the articles, but now I rely more on tables with a clear presentation of the result values and specifications, which later also ensure a better comparison of the maps among each other.



Specifications and picture gallery

The design is based on older versions and is new. These include the LED applications on the card and the top with the illuminated lettering and the backlit logo in the backplate. The rest is made of heat sink and plastic, as well as a 3-fan design.

GPU-Z gives us a first overview of the other technical data:

The table gives a nice overview of the remaining technical data of the current and older comparison models:

Test system and measurement methods

The test system and the methodology are well known, but since I now test independently here in Germany, the test system has also been upgraded once again without having to take into account the former US colleagues.
