Hoping to summarize here...
If the goal of the OP is to compare to what we saw with Zen, then we need to run 2.77 and 100 samples (which would render this thread useless for that idea). That said, I have now tested on TWO systems (6950x and 6700K) 2.77 and 2.78 and there is not a time difference (within a margin of error, less than .5% difference in my times - not consistently slower/faster either).
This thread is good for running 2.78 at its default settings. If you want the most apples to apples you can get, it would be how I mentioned it in the previous paragraph.
Well a 3570k stock is 6 seconds slower than a 4790k at 4.4ghz and 8 slower than a 4770k at 4ghz
4790k at 4.4 lost to the 4770k at 4..
Work that one out.
You need to compare side by side those platforms, there could be many reasons that is happening.
Either way, the OP needs to get in here and clear this mess up, LOL!
