Tests of video cards Intel Arc A750 and A770 showedthat in general these are good solutions for their money, but not without drawbacks. For example, compared to competitors, Intel’s new products have a slightly increased power consumption under load, and in idle time the difference is about four times. And Intel, apparently, itself can do nothing with it.
In idle, the new Arc consumes about 40-50 watts versus 7-10 watts for competing adapters from Nvidia and AMD. This problem can be solved, but Intel cannot do it, so she explained how users can do it themselves.
Firstly, in the BIOS settings of the motherboard, you need to set the Native ASPM value to Enabled, and secondly, enable the PCI Express root port ASPM and select the L1 Substates value.
In Windows, you need to find the “Power and sleep” section in the system settings, go to the “Advanced power settings” section, select the power scheme used, go to the “Change advanced power settings” item, find the PCI Express item there, go to the Link State item Power Management and select maximum power saving.
How much this will reduce the idle consumption of Arc cards remains to be seen.
