I have an Intel 8700K CPU but only use my AMD RX380 4GB GPU for editing and renders. Is there a distinct IQ/workflow performance advantage using either or both the Intel iGPU along with the AMD discreet GPU?
Intel QSV is the superior hardware encoder, & RX380 the superior GPU for processing.
If you have a 10 series Nvidia card or newer you don't really need intel QSV although some users here have stated in their opinion QSV has the highest video quality. If you had a 1080/ti you have the dual NVENC's & so more reason to not use QSV as hardware encoding is twice as fast.
Don’t speculate. Measure it yourself.
So I've finally gotten around to getting the iGPU seen via attaching one of my monitors to it (seems it's not seen by Windows unless a monitor is attached to it).
I used the standard 1080-29.97 8 bit template and render out (One track has Neat Video applied at the track level) - let's just say alot faster than using VCE! I even went so far as to set the project properties to 32 bit just for giggles - rendered about the same speed as an 8 bit VCE encode - pretty amazing actually.
MAGIX AVC-QSV - 1:33 sec
MAGIX AVC-VCE - 1:58 sec
Now the downside - the QSV version seems to be washing out my highlights. The AMD VCE encodes do not appear to exhibit this issue.
Any ideas?
