Review: Sapphire Pulse RX 7900 GRE Gaming OC


Temperature and consumption:

Temperature :

To record temperatures, we opted for the Superposition stress test in Extreme mode. We opted for three 5-minute runs with 10-minute intervals between each test. We took advantage of this benchmark to record the graphics card’s power consumption for the table above.

To find out the Idle temperature, after completing the three stress test loops, we let the card rest for 20 minutes before taking the temperature reading. Bear in mind that most boards benefit from “0 dBa” technology, so the fans cut out below a certain temperature, often between 50 and 55°C. It therefore takes longer to dissipate heat after a period of stress testing or gaming. A card that does not benefit from this technology will be noisier than others at rest. A quick reminder: our temperature readings are taken in Open-Air. In a closed case, the cards will inevitably be warmer.

Although not the best in its class, our Sapphire’s cooling system is efficient, keeping the GPU and the various PCB components at the right temperature. The fans are relatively quiet and never run at maximum speed.

Power consumption (whole configuration) :

We use a wattmeter to measure power consumption at the output of our power supply. Our modular power supply is a CORSAIR AX1600i. The result is the average total power consumption of our configuration. Only the graphics card changes between each reading. So it’s easy to calculate the difference between each graphics card.

But the good news is that we should (finally) be properly equipped to isolate power consumption solely from the graphics card, as we have pre-ordered the BENCHLAB from Elmorlabs.

Power consumption was 376 watts for our complete configuration, the same as that obtained with the PowerColor RX 7800 XT Red Devil graphics card.
