NVIDIA GeForce RTX 4080 Founders Edition Review

NVIDIA GeForce RTX 4080 Founders Version Overview

Posted on

GPU clocks are slightly larger from the RTX 4080 FE, in comparison with our RTX 4090 FE pattern, and energy draw is certainly about 25% decrease. We didn’t fairly hit the 320W TGP of the cardboard, coming shut solely with a momentary studying of 318.9 watts – which was an outlier as all different outcomes had been 313.9 watts or decrease.

Now we are going to transfer on to a protracted part about thermals and fan speeds.

In the course of the 10x iterations of the Metro Exodus benchmark (3440×1440, excessive preset) our RTX 4080 Founders Version pattern was a really cool-running card, and the followers weren’t noticeable over CPU cooler noise. These 40 Sequence Founders Editions are very quiet playing cards, and in some unspecified time in the future I must implement an ultra-quiet (or passive) CPU cooling setup to permit for correct GPU noise measurements.

The RTX 4080 FE registered a max 60.6 C GPU Temperature, and 70.7 C Sizzling Spot, as reported by the cardboard and captured by way of GPU-Z knowledge logging. The room throughout these exams was slightly below 19 C (~18.8 C), which is a number of levels cooler than our RTX 4090 FE testing (~21.5 C ambient), so deltas makes extra sense.

Evaluating delta temps, then, we discover that the RTX 4080 FE produced a max of 41.8 C GPU / 51.9 C Sizzling Spot, whereas the RTX 4090 FE produced a max 45.5 C GPU / 55.3 C Sizzling Spot. These barely cooler temps make sense contemplating a smaller, much less power-hungry GPU is being cooled with a thermal design created for the RTX 4090 FE’s huge 608 mm^2 GPU and 450W TGP.

Please notice, nonetheless, that the RTX 4080 FE’s use of this cooler will differ in that the fan speeds are decrease by default, because it has much less of a thermal load to take care of. I recorded a max fan 1 velocity of 1421 RPM, and max fan 2 velocity of 1326 RPM from the RTX 4090 FE underneath load. This RTX 4080 FE, then again, had a max fan 1 velocity of 1275 RPM, and max fan 2 velocity of 1223 RPM underneath the identical situations.

Not an enormous distinction, however nonetheless about 10% decrease fan speeds on common and barely higher temps.
