Sapphire Radeon RX 5700 XT Pulse Review – Navi with certain vibrations

Sapphire's first Navi card is with the Pulse actually the entry model, if one follows the previous nomenclature of the manufacturer. This also entails compromises and today we will sound out which and what this means for the customer.

The title sounds funny? I’ll come back to that, I promise. But first, we’ll look at the exterior and data of the dual BIOS card. At least that’s where Sapphire didn’t save money. Compared to the already tested Red Devil by Powercolor and the Evoke by MSI (including the efficiency mod), the Pulse has to make a lot of effort. But always nice one after the other…

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 Pulse versions and is not really new. Sapphire has probably done without LEDs for reasons of cost. This isn’t really a disadvantage, as there are enough interested people for a darkroom in a closed case. If you don’t have a transparent side panel: here’s a card without a squeaky colorful photon gun.

Matching the promised overview of the most important features:

Length (outer edge of slot bracket to end of card) 25,5 cm
Installation height (upper edge of PCIe slot to upper side of card) 12,8 cm
Front mounting depth (cooler body to underside of circuit board) 4,0 cm
Rear mounting depth (board to outside of backplate) 0,5 cm
Weight 919 g
Shroud Anthrazit
Keine LED
Connectors 3x DisplayPort 1.4
1x HDMI 2.0
Other Features Dual-BIOS with Silent-Mode

An initial overview of the further technical data of both BIOSes is provided by our MorePower Tool. First the similarities, which are the same in both settings:

Now let’s get to the power and the voltages, where there are some slight differences. On the left the OC (Standard) BIOS 1 and on the right the silent version from BIOS 2:

There are hardly any differences with the fan settings, only the target temperature is set somewhat lower with the silent variant:
