The Radeon RX 7900 XTX Gaming OC from Gigabyte is among the more affordable models which are rarely reviewed. Manufacturers lower production costs mainly by reducing the size of the heatsink. As a result, these cards don’t perform as well as premium high-end models in thermal and acoustic tests. However, their lower price makes them popular not only with individual buyers but also OEMs assembling prebuilt PCs.
In the silent mode Performance is almost the same. I would attribute the 1.2 fps performance difference to measurement error rather than higher performance of OC mode.
The average clock speed has remained virtually the same.
The power consumption of the card measured by the monitoring sensors is kept at the set limit, which is the same as in OC mode. The average power consumption of the whole build differs by less than 3 W, which is also more likely a common measurement deviation.
What differs more is the temperature, especially the hotspot, which is already reaching 94 °C. This is due to the lower fan speeds caused by moving the fan control curve down to lower speeds at the same temperatures.
Fan speed fluctuations are slightly higher, overall values are significantly lower and the card is quieter.
