I have been running programs that are single threaded that I expected to run better on the AMD FX-8350 4000Mhz than they have been running. I was starting to think I had a lag issue with hardware. But then I read this and it shows why its lagging. While the FX-8350 is ok for programs that are multi threaded, its lagging in single threaded performance. I didnt buy the FX-8350 for single threaded computing, but have been WORKING on a project and its the most powerful system available to crunch and so I have been using it and I have been running 8 copies of the same program I wrote each core working on 12.5% of the total work load so I can put all cores to USE vs pegging 1 of 8 cores and wasting processing time. I expected some work to complete faster than it has and thats when I started google searching and found this...

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two GENERATIONS. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more CAPABLE multi-threaded server orientated performer. The AMD is also cheaper but significantly more power hungry which counts strongly against it as a sever proposition. The FX-8350 could be a GOOD fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance.
