Power draw, thermals, and synthetics
We also tested the GeForce RTX 2080 Super Founders Edition using 3DMark’s highly respected Fire Strike synthetic benchmark. Fire Strike runs at 1080p, Fire Strike Extreme runs at 1440p, and Fire Strike Ultra runs at 4K resolution. All render the same scene, but with more intense graphical effects as you move up the scale, so that Extreme and Ultra flavors stress GPUs even more. We record the graphics score to eliminate variance from the CPU.
We test thermals by leaving either AMD’s Wattman (for Radeon GPUs) or EVGA’s Precision X1 (for GeForce GPUs) open during the F1 2018 five-lap power draw test, noting the highest maximum temperature at the end.
We test power draw by looping the F1 2018 benchmark for about 20 minutes after we’ve benchmarked everything else, and noting the highest reading on our Watts Up Pro meter. The initial part of the race, where all competing cars are onscreen simultaneously, tends to be the most demanding portion.
Unsurprisingly, the more powerful, faster-clocked RTX 2080 Super draws more power and runs hotter than its vanilla namesake. The dual-axial cooler design finds a comfortable middle ground: It’s not quiet, but it’s also not annoyingly loud. Custom cooler designs should bring the overall temperatures down quite a bit.
