Powercolor RX 5700 XT Red Devil under test – force is mass times acceleration

What’s the best way to annoy your competitors? By impressively showing who has the longest and greatest. And if you are a bit more subdued when it comes to price and can score points with features, then a product almost sells itself. Too much praise in advance? Honour to whom honour is due, but you’re right. That should 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 to get to the point a little bit more, I have kept the structure of the articles to a large extent, but now I rely more on tables with clear representation of the result values and specifications, which later also guarantee a better comparison of the cards among themselves.

 

 

Technical Data and Picture Gallery

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

Matching the promised overview of the most important features:

Length (outer edge of slot bracket to end of card) 30,0 cm
Installation height (upper edge of PCIe slot to upper side of card) 12,5 cm
Front mounting depth (cooler body to underside of circuit board) 4,57cm
Rear mounting depth (board to outside of backplate) 0,5 cm
Weight 1248 g
Shroud Anthrazit
ABS injection moulding
LED (Logo, Stripe)
Connectors 3x DisplayPort 1.4
1x HDMI 2.0
Other Features
Dual-BIOS, OC and Silent Mode

GPU-Z provides us with an initial overview of the other technical data:

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