Review: ASUS TUF Gaming RTX 4070 SUPER 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.

Not surprisingly, temperatures are higher than on the RX 7800 XT, but the heatsink on our sample of the day is thinner. The card is perfectly silent and temperatures remain perfectly contained.

Power consumption (full 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 is unsurprisingly higher than that of the RTX 4070, rising from 284 to 333 watts for our complete configuration. Based on a similar architecture, this 16.5% increase in power consumption almost matches the performance increase we noted.
