Power and Temperature

To test the power and temperature we perform a manual run-through in Cyberpunk 2077 at “Ultra” settings for real-world in-game data.  We use GPUz sensor data to record the results.  We report on the GPUz sensor data for “Board Power” and “GPU Chip Power” when available for our Wattage data. 

GIGABYTE GeForce RTX 3090 GAMING OC Board Power Draw Graph

Above is the Board Power Draw compared via GPUz. The Radeon RX 6800 XT does not reveal Board Power via GPUz. You can see that the GIGABYTE GeForce RTX 3090 GAMING OC does consume more board power than the GeForce RTX 3080 FE, about 10% more power. Considering the uplift in performance we got, this isn’t bad. Overclocking the video card upped power another 10%. It does consume a lot of power when you start overclocking and especially by it upping the GPU Voltage.

GIGABYTE GeForce RTX 3090 GAMING OC GPU Chip Power Draw Graph

Now we are looking at GPU Chip Power Draw reported by GPUz. You can see that the Radeon RX 6800 XT is off the charts, it’s massively higher in GPU Chip Power Draw. The GIGABYTE GeForce RTX 3090 GAMING OC actually has a lower Chip Power draw compared to the GeForce RTX 3080 FE. This is mostly likely due to the lower clock speeds that it sustains compared to the RTX 3080. But when we overclock it, then it exceeds GPU Chip power over the RTX 3080, but not by a lot. The Radeon RX 6800 XT is still way up there in GPU Chip power draw.

GIGABYTE GeForce RTX 3090 GAMING OC Temperature Graph

With the GIGABYTE WINFORCE 3X cooling system the GIGABYTE GeForce RTX 3090 GAMING OC keeps a very cool GPU at 62c. This runs cooler than the GeForce RTX 3080 Founders Edition by a lot. It’s also cooler than the Radeon RX 6800 XT. When we set the fans to 100% and overclock it GPU temp falls to 53c. We can say that the cooling system is not holding back overclocking potential. GIGABYTE has built a robust cooling system for the GeForce RTX 3090 GPU. It also runs quiet at default operation, and even at 100% the fans weren’t as loud as we would have thought for having 3 fans.

  1. Seven months to review a GPU that is essentially impossible to buy in retail, seems about right.
    The review is well done as usual.
    The availability is disheartening.
  2. Thanks @Brent_Justice for the great review. I’m not a fan of the block-styled design of these cards but its good to know they’re up to par. After all, most don’t buy cards to look at them.
