Intel Fixes Arc GPUs' High Dual-Monitor Power Consumption, 3+ Monitors Still a Problem

Multi-display configurations are used by many people in the small office/home office space (SOHO) these days. Intel's moderately-priced Arc A770 graphics cards would be a good fit for these setups if they did not consume 40W of power in idle mode when driving two or more monitors. Apparently, the latest drivers fix the issue and cut down power consumption by four times, reports VideoCardz. But there is a catch. 

Driving several displays at once requires powering up the appropriate number of display pipelines that consume energy. Also, sending high-resolution images with deep colors to monitors requires transferring loads of data and this means power. But in idle mode GPUs don't need to send 60 or 120 high-resolution deep color images per second to displays, which is something that Intel's Arc-based graphics cards did (and competing products from AMD and Nvidia do not).

    To be fair, even Nvidia occasionally has trouble with multi-monitor power consumption:

  • I really hope Intel will release Arc A5xx for 1080p gaming. I'm sick of what nVidia and AMD are doing with their latest GPU's. We need Intel, but not A380, or A750/770 which is too expensive for 1080p gamer.

    There isn't going to be an A5xx, tommo1982.

    The good news is that an A750 is currently $250.

    AMD has the same issue with high refresh rate setups, my idle GPU consumption doubles/triples if I turn on >60 fps on my dual monitor setup on the 6700XT

    Seems like this is the kind of problem that should have had a solution that came direct from the iGPUs with little new work.

    Obviously its not that simple.
