Today I replaced my old Phenom II x4 840 with an AMD FX 4130. The new cpu compared to my old, runs 600mhz faster stock, has an l3 cache unlike the other, and is much newer. After my excitement was over and my pc was booted, I reran the Windows Assessment test and much to my surprise, my cpu score went from 7.3 to 7.2. I figured this was just an issue with that and I ran 3dmark. My overall score dropped almost 400, and the physics score dropped by 1000. In confusion, I went into the bios and disabled c1e, c6, and APM. Re ran the tests and still the same speed. The processor is always at the stock speed and is unparked, so why is it slower exactly? Is it maybe just slower in certain operations, or do I have something set wrong. The temperatures are also very good, 55 c average under load and 30c idle. I ran passmark performance test and I score 4185 for my cpu. The reported score online by passmark for my cpu is 4194, so that is good. Any explanations and ideas for the lower scores? thanks!

The 4130 is slightly better for single threaded performance but slightly worse for multiple threads: http://www.cpu-world.com/Compare/191/AMD_FX-Series_FX-4130_vs_AMD_Phenom_II_X4_840.html

 

Depending on what you do with it, you might see performance increase or decrease. It seems all of the benchmarks must be making use of all cores of the cpu which means your new one will be slower. Clock speed alone is not an indication for performance. Work per clock cycle varies between cpus.

So would you  say I downgraded, or should I not worry?

I would say it depends on what you are using it for. Minecraft is an example where you might benefit, some more modern games you might see a decrease in performance.

FWIW:  If you want to see a comparison of the two CPUs (I'm not saying that it's a meaningful one), you might visit the CPUBoss website.

I tried that out, it gave me a good idea. In the end, im not too bothered by the potential loss in performance, as while ive lost some, ive gained more. On top of that, this cpu has lots of overclocking capability to my understanding, unlike my previous.
