At first glance, the Gigabyte GeForce RTX 5080 Gaming OC doesn’t impress with a flashy design or a vibrant light show. It’s not among the cheapest models, but it’s far from the most expensive. In a standard position, the lighting is rather subtle, the backlit fans stand out more in a vertical setup. The real advantage, though, is the oversized cooler and well-tuned fan control, allowing this card to surpass even more expensive competitors in terms of operating characteristics.
I measured the operational characteristics during the Cyberpunk benchmark with RT Medium settings at a resolution of 3840 × 2160. With this setup, the graphics chip is almost fully loaded even with the performance BIOS. I did eight consecutive benchmark runs.
The graph always shows the last run, from which the average value for a warmed-up card is calculated.
Below you can see why it makes sense to switch to the quiet mode with this card. The difference in performance is at the level of measurement error, the same goes for clock speed or power consumption.
With this setup, the card’s average power consumption is around 347 W, according to the monitoring.
The total power consumption of the PC, measured with the UT71E multimeter, is shown in dark color. The green line represents the power consumption of the card based on monitoring, and the blue line shows the processor’s power consumption according to monitoring (measured through HWiNFO).
The chip’s temperature rose only slightly, by 3 °C.
However, the fan speed went down significantly and with it the noise level of the card. It gets to 1300 rpm, which is quite a luxury given the performance of the card. It’s not absolutely silent, but in most cases the noise will blend in with other fans.
