i have a dell vostro 3550 laptop with amd graphics and intel hd 4000 (or something)
heres what i want to know. even though amd has now included the option to switch graphics based on power source (battery or plugged in) and it works just as well as the setting based on application needs
but i was wondering, i usually use my laptop while plugged in, so therefore based on my power source, my laptop always keeps the amd card switched on, while it definitely provides much better performance, im concerned if using it constantly (as i said i rarely use my laptop on battery) will decrease its life significantly. "significantly" being the keyword, ofcourse using anything will wear it.
on the other hand, if i set my switchable graphics method to switch on application needs, ive noticed that if i assign, for example SKYRIM a high performance setting, it definitely runs alot smoother than power saving setting, but suppose i assigned VLC player a high performance setting (humor me) and power savings settings to google chrome, will both my GPUs be working (when vlc and chrome are being using at the same time), one assigned to chrome while other assigned to VLC or will AMD (high performance) just take over whenever an application with high performance setting is running
i know this was a long post but i was just trying to be as detailed as possible
