Hey all, I know that switchable graphics is a thing in laptops where there is usually a single port. But how would you go about it on desktop? Do you put your monitor in the onboard HDMI or on the dGPU port? There are other issues associated with doing it of course, but I thought it might save on power and noise if I used the iGPU as much as possible.
Only have a nvidia GPU at the moment, but hoping to get an AMD 9070 at some point
Get a wall plug power meter and check for yourself. It’s a cheap investment and always fun to be able to check the power draw of different appliances once you’re done testing your computer. :)
From my experience there’s little power savings in your scenario.
The idle power consumption for a GPU tends to be pretty low these days. The only major issue is running multiple monitors with different vertical timings. That will lock the VRAM frequency to maximum and use a lot more power.
Oh I gotta check this, I’ve always been running a slower screen alongside the main 144Hz one but this is the first time I hear about it affecting power draw this way.
Yea that’s what I kinda figured to be honest. Probably the only scenario would be wanting to do pass through to a VM or something where it might be useful
