NVIDIA GeForce RTX 4080 Founders Version Assessment

GPU clocks are just a little greater 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 have been 313.9 watts or decrease.

Now we’ll transfer on to a protracted part about thermals and fan speeds.

Through 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 should 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 through GPU-Z information logging. The room throughout these checks was slightly below 19 C (~18.8 C), which is a couple of levels cooler than our RTX 4090 FE testing (~21.5 C ambient), so taking a look at 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 massive 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 pace of 1421 RPM, and max fan 2 pace of 1326 RPM from the RTX 4090 FE beneath load. This RTX 4080 FE, alternatively, had a max fan 1 pace of 1275 RPM, and max fan 2 pace of 1223 RPM beneath the identical situations.

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