i7-5930K Rig Barely Outperforming i7-4700MQ Laptop In Video Encoding/Authoring.

So I pulled the trigger on an i7-5930K rig. System includes Asus x99 Deluxe, 4x4Gb 2400Mhz DDR4 ram, 1000W EVGA Supernova Gold, H105i water cooler, SX900 256Gb SSD and a pair of R9 270 in crossfire.

Problem is, it's barely outperforming an i7-4700MQ laptop with only 8Gb of DDR3 and a non-SSD drive. At most, the i7-5930k system is 15% faster when I ran Nero 12 and AVS Video converter. Even turning off the energy saver mode on the 5930k and overclocking it from 3.5 to 4.1 Ghz barely made a dent in improving computational time.

Any ideas of what might be causing a bottleneck?

Can't see the absence of Quicksync on the 5930k is causing these disappointing results.

Quicksync can make a huge difference in performance.

However, CPU encoding will usually give much better quality results than Quicksync encoding. It just depends on what you want. Do you want high speed, high quality? 5930k will do it. Do you want high speed, low quality? Quicksync will do it.
 
Video software might only use a couple of cores =)
Could be the clock rate of 3.0 GHZ

I expect this to be the problem. I would check to see how many cores sit at 100% during encoding.

Just ran the test again. All 6 cores were at 100%. Is that normal? Before I lost my i7-3770k system in the fire, the 4 cores never even came close to 40 or 50 percent usage running the same software.
 
Pretty sure it's something to do with Quicksync. If you have a chip with an IGP try turning Quicksyn on and off and see if it makes a difference.

Fairly sure that was due to your 3770k using quicksync. Video encoding is generally highly parallel, thus able to maximize use of all cores. The fact that it wasn't doing so on your 3770k is a huge indicator it was using quicksync.
 
I don't know why use CPU to encode videos in 2014.
There is GPUs that are incredibly faster in this job, use a software that use CUDA or OpenCL and leave the CPU alone.

please post the software that can encode x264 on a gpu in linux

if you care about the quality of your output, cpu is still king. software > quicksync > nvenc/cuda, in my professional experience. i'll encode personal stuff, or a quick and dirty sample on gpu, but my finished products always get done by cpu.

GPU can render at the same quality of the CPU.
There is no sense in saying that CPU do it better.

Not completely true... can depend on the scaling algorithms as not all run on GPU. GPU encoding is still far more limited compared to CPU. For non-pro projects, sure, it's fine.
