Intel Ruixuan A770 / A750 series graphics cards idle power consumption up to 47W

After the Intel Ruixuan A7 series, high-end desktop graphics cards were released, some evaluations found that the card still consumes 47W in an idle state, while generally speaking, it should be less than 10W, which is obviously abnormal of.

As can be seen from the figure, the idle power consumption of Intel Ruixuan A770 and A750 is much higher than that of RTX 3090 Ti.

On October 13, Intel gave a solution on its official website, requiring users to configure the BIOS and Windows power settings.

BIOS settings:

  • Allow the OS to control ASPM by setting Native ASPM to Enabled.
  • Enable PCI Express root port ASPM and select the L1 substate.
If you are not sure where to find these settings, you can consult the motherboard manual or contact the motherboard manufacturer. Different manufacturers may have different names on the same setup.

Additionally, users need to configure Windows power settings:
  • Win + S Search for "Edit Power Plan"
  • Click Change advanced power settings
  • Find PCI Express
  • Click the "+" sign next to PCI Express to expand the options
  • Click the "+" sign next to Link State Power Management to expand the options
  • Use the drop-down menu to select Maximum Power Savings
  • Click Apply at the bottom right to take effect
Intel says its power management architecture is designed to target technologies that exist on modern platforms and benefit from a specific parameter in the motherboard's system settings commonly known as ASPM. Enabling these features will allow users to get the best possible idle power consumption with Intel Sharp Graphics.

If the display refresh rate exceeds 60Hz, the GPU will be required to run at a slightly higher clock, and slightly higher power consumption is normal. Intel said it will look to optimize in the next generation.
