HEVC encoding on 8th generation

[Paul Anderegg]

I am looking to upgrade my old i7-3700/GT730 spare Windows 10 rig with a new version that can play double duty as an HEVC encoding platform. My primary PC is for Media Center use, and is relegated to using 6th generation on Windows 7.

So, HEVC encoding with Quick Sync uses hardware...am I correct in assuming that encoding speed would be the same indifferent to whether I use an i3 or i7 8th gen CPU? Core count, Hyperthreading, GHz, any of those work in favor of the hardware used for HEVC encoding at all? Would be nice to also be able to do 10 bit h264 encoding for HDR...I do not believe 8th gen do 10 bit HEVC hardware encoding?

1) Yes you are although higher level CPUs have better iGPUs more EU units and better clocks,I'm not 100% on this one but I think in has quite some impact.

Some software will use the CPU as well

others will only use the iGPU

Funnily enough you get the same speed...

But you can just put a nvidia card into your current system, it puts the intel iGPU to shame (well not really, considering the price difference,the iGPU is "free" )

But you can't get Quick Sync on an Nvidia...I pulled a GTX1050 out of my Media Center rig because it wasn't providing me with anything. I can understand a GPU would enhance timeline playback when putting together clips, but I am looking for h264 and HEVC transcoding, with Handbrake, for HDR uploads to YouTube. My current HEVC platform is my Macbook Pro, which with it's amazing software encoding, renders 1 second of HEVC material per 1-2 minutes. Quick Sync Handbrake transcodes are brutal fast on my i7-6700k...as long as I am spitting them out in 50-100Mbps, I don't have any perceivable quality loss over CPU transcodes. :-|

No you get nvenc with nvidia,same thing different name,it provides you with accelerated transcoding look at the video.
If you want a nice interface to use with nvidia you can try avidemux.

I'll have to look more into Avidmux...my GTX1050 is collecting dust ina closet, maybe I can use it...will Avidmux do 10 bit h264 or encode 10 bit HEVC with Nvidia?

No,only the normal kind,no 10bit.
Handbrake will do 10bit for quicksync,even on the g4560.
