No pun intended
I’m just curious about a detail. If no VGA is installed in the computer, because the one included in Sandy/Ivy bridge CPUs is used, when all GPU cores are used for encoding purposes, is the computer still usable? I mean is it still possible to watch a clip from youtube for example or using the browser while the machine is busy with video encoding? Even more: is it still possible to watch a movie with VLC for example while the machine is encoding?
I know that quick sync allow to encode a full movie in a matter of minutes (thanks Dee for posting test results ), but what happen if you keep the machine busy for a couple of hours?
Moreover, what happen to quick sync if a discrete VGA is installed? Is it still possible to use the Sandy/Ivy GPU cores for video encoding when a discrete video card is installed?
I almost forgot: I’m referring to a system with Z77 chipset
Just for comparison, my current system (Intel E8400) allow me to watch a movie with VLC when Handbrake is working without any problem (no stuttering, no pixelation). Handbrake process priority is set as normal, so even if it using the CPU at 100 the machine is still usable.
I have a pretty basic VGA installed in my computer, a nvidia 8500GT, not exactly the most powerful video card available, but is still able to manage VLC playback when handbrake is running using the CPU at 100%.
