3930k Render Times

[TheMoInMo]

Hey guys, so today I have a question about my CPU. I am currently running an i7 3930k at stock speeds, and i am rendering a 6 minute video at 1080p 30fps, and it is saying that it will take almost 12 minutes to render. This seems long considering I essentially have a 12 core CPU. Am I just expecting too much, or is my computer really running slow for a 3930k? Thanks

Idk if it's normal, but I still highly advise you to overclock the CPU. You're going to benefit from it.

not enough info,what program do you use and what settings do you render at

I have the same chip, as long as they have decent cooling you should easily be able to push +1000mhz without much overvolting, if any.

 

Its multithreaded performance is pretty close to a skylake i7...

This is way too little info to go on.  That might be great or terrible.  No idea.

I am using Sony Vegas Pro 13, with the MainConcept AVC/AAC (*.mp4;*.avc) on the Internet HD 1080p preset. Do I need to give my whole system specs? would that help?

Thanks, that is better.  I don't know if we need full specs but GPU would be important if you're using any hardware acceleration.

Unfortunately I can't really comment though since I only have experience encoding on premiere/Adobe Media Encoder.

I have a GTX 780

It's actually faster than a skylake i7 multithreaded-wise 8-15% depending on the OCs (8% stock)

So I was never told, is this average for a stock 3930k?

Luke JUST did a video on this misconception... *eye roll*

 

Okay, let's go over some things.  Firstly, you haven't said what program you're using and the efficiency of implementation for video compression can vary widely by software.  This also depends on if you're doing a straight encode of video or if there's a lot of processing going on, like a render of an editing or compositing program that applies different effects.  It's also important to note that video encoding and even rendering is not necessarily 'embarrassingly parallel' meaning getting a great amount of efficiency across multiple cores may not happen.  I've seen plenty of Nuke scripts use up relatively little CPU power, but only because the scripts are so heavily dependent on I/O that the system's I/O throughput is unable to even get close to saturating the CPU.
