Theoretical exercise for a power efficiency afficionado such as myself.
Can you use in a single monitor setup a discrete GPU (for convenience, let's say my RX 6800) strictly for gaming and the integrated GPU of a say Ryzen 7000 series processor for everyday applications (office stuff, browsing, desktop idling etc.).
I have scoured the internet for this and please do correct me if I am wrong, but apparently you can play with power plans and set a plan to use the dGPU and another to use the iGPU and you would just switch between them depending on your needs. But is this a seamless operation, are there any downsides in terms of system stability, driver issues, something else?
*save for video playback (youtube, Netflix) which seems kinda high at around 45 watts, I am satisfied with the power efficiency of my card, but hey, if I can dump less heat in my room worth on average 35-40 watts, in a distant future build, why not do it?
