I'm transcoding a lot of video using Intel's Quicksync via Handbrake. Does anyone know if there will be a benefit of overclocking the onboard graphics chip? I know I can get more FPS (but I use discrete cards for that).
dont overclock onboard. if you do a lot of transcoding get an nvidia card and take advantage of their Cuda technology (it basically takes the load off the cpu and makes your dedicated graphics do the video intense tasks)
huh? Quicksync is a dedicated hardware encoder and does not run on the iGPU so overclocking the iGPU will have 0 effect to my knowledge.
As said, Handbrake does not use quicksync, only the cpu so overclocking the cpu is one of the ways to improve performance. You can also improve performance by adding drives so that source and destination are not on the same drive. This way one drive wont have to split its bandwidth between reads and writes. Remember everytime the heads have to move theres an average of about ~12ms to do so; not only do you cut your data bandwidth in half for read and writes you add in a delay and end up with read, delay, write, delay, read, delay, write, delay... its also recommended to have a seperate boot drive.
