Energy consumption and efficiency:
At last, we have the means to effectively monitor the power consumption of our graphics cards, thanks to the Benchlab telemetry system. We will now be able to carry out a complete analysis of our graphics card’s total power consumption via the dedicated 3 x PCIe and 2 x 12VHPWR power cables. But that’s not all, as we also need to be able to measure the power supplied via the PCIe slot. So we’re going to use a PCI-E PMD adapter from the ElmorLabs store. This will enable us to measure the overall power consumption of the graphics card under test in a totally independent way. Here’s a series of photos of our Benchlab installation, to which we’ll be devoting a dedicated test in a few weeks’ time.
These various readings will be taken via Benchlab’s dedicated application. The photos below were taken with the NVIDIA RTX 4060 Ti 8 GB FE graphics card to illustrate our power consumption readings.
To obtain the total power consumption of this RX 9070 XT, we’ll record the 3x8PIN Power consumption, which corresponds to the card’s power supply via its 16-pin mini-connectors, and the EPS1 reading, which supplies the adapter. We export the readings, which are taken every 500 ms, and calculate the average consumption in the Cyberpunk 2077 game in 4K rasterization with graphics options in Ultra
Power consumption in Cyberpunk 2077 :
Very good placement in terms of power consumption for our Gigabyte RX 9070 XT Gaming OC, which certainly consumes a little more power than the RTX 5070 Ti, but offers excellent performance.
