Power and Temp
System power is measured at the wall in Watts and represents the total system load. Our power supply is a Seasonic Prime 1000W Titanium. Temperature is measured via GPUz and room temperature of the testing rig was at 70F while testing.
Lowest Wattage is better of course, and the AMD Radeon RX 5700 XT pulled in the lowest at 352W. However, it was also the slowest video card in the mix. According to this graph, you do get what you pay for. The fastest video card was the ASUS ROG STRIX RTX 2080 Ti O11G GAMING and it was also the one that required the most Wattage. Below that is the GeForce RTX 2080 FE, so the scaling we are seeing here makes sense.
Overclocking the ASUS ROG STRIX RTX 2080 Ti O11G GAMING also increased the GPU Voltage. Due to this, there was a large power jump from 403W to 473W with it overclocked. It ate a lot of power but was also extremely fast when overclocked. The power numbers make sense.
In terms of GPU temperature though, the opposite is true! The hottest GPU (which was the slowest) was the Radeon RX 5700 XT. Its cooler just isn’t that efficient. NVIDIA’s cooler design does much better and kept the RTX 2080 FE at 73c.
What really took the cake though was the robust and custom design of the ASUS ROG STRIX RTX 2080 Ti O11G GAMING video card. The custom cooling on it was the best. It kept the RTX 2080 Ti GPU at a cooler 60c even though it was eating more power and delivering more performance. Those are good temperatures.
When overclocked we had the fans at 100% while it was eating a lot more power and Voltage, yet it stayed under 60c at 57c. The temperature was not holding this video card back; the thermal solution was not holding temperature back or overclocking potential.
