Maybe use a Pro rather than an Evo.
Better yet, try using two Samsung Pros.
are you using denoiser? what effects? what rendering type? is it 50% all cores?
It all depends on your media and what you are doing to it.
Here is a 100% CPU export:
This is an export from my Premiere Pro BenchMark (PPBM) using Premiere 10.3 on an overclocked i7-5960X without any GPU assistance. Next you will see the same timeline exported much, much faster with assistance from my GTX 970.
Here is another run, again the same timeline, with the GPU showing the 99% utilization of the GPU.
I am having a similar issue.
I just built a new computer:
Windows 10 Pro
Intel Core i7-6700K CPU @ 4.00 GHz
32 GB Ram
I just installed Premiere Pro CC 2015.3
Direct export or AME runs insanely slow when exporting Windows Media HD 1080p 24. CPU stays around 40-50%, Memory around 25%. Takes 1 hour to encode a 30 minute video. My previous computer was much slower and ran Premiere 5.5 and encoded 5 times faster. Any recommendations would be greatly appreciated.
The major problem that I see is your Task Manager picture shows 138 processes running while mine only has 64. Turn off all those unnecessary processes.
Have you removed the checkmark on the Intel h.264 acceleration?
What GPU? Is it working?
