Depends a lot on the load
Depending on amount of threads and emphasis on them, you could have this situation for example:
Load A runs faster on CPU 1
Load B runs faster on CPU 2
Load C runs about equally as well on both
Also, you have an interesting situation with Bulldozer arch and the improved versions - Every module shares resources on two threads.
That creates a situation where you would think, traditionally - an 8 core CPU @4ghz won't beat a 6-core CPU @4ghz if you're only using four threads!
However that's not true for Bulldozer/Piledriver/Steamroller etc. On an fx6300, you have 3 modules. If you have 3 threads, one goes to each module. If you get a fourth thread, two of them have to run on the same module and share resources, which can give no slowdown (optimally) or a lot of slowdown (lots of conflict with resources)
On an fx8320 at the same clock speed, that fourth thread would just jump on the fourth module, and it can't be slowed down by having to share anything.
That does not come into practice much, but it's to show that you can get benefit from an fx8320 over a 6300, even if you're only using 4 threads for that particular workEdited by Cyro999 - 4/2/14 at 10:49am
