For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we ran Battlefield 1 at 1920 x 1080 and recorded the peak power number while gaming a particular level that we test on each card. Our idle numbers are high, but keep in mind that we are using a workstation motherboard that has two 10GbE ports and other high-power draw controllers on it.
Power Consumption Results: With the AMD Radeon RX VEGA 56 video card installed in the system we topped out at 457 Watts when running BF1 at 1080P resolutions. The AMD Radeon RX 64 video card used 510 Watts in the same test, so our testing shows the VEGA 64 uses about 65 Watts more power than the VEGA 56 while gaming. The AMD Radeon RX VEGA 64 power efficient card uses more power, makes more noise and got beat by the NVIDIA GeForce GTX 1080 Ti Founders Edition in every benchmark. The NVIDIA GeForce GTX 1080 Ti is not going to be dethroned today!
Let’s wrap this review up!
