It's not about what the game recommends, it's about how many threads the game engine can actually spawn and whether or not spreading them to more than 4 cores has any impact on performance. Often, the FX-6300 and FX-8320 will outperform the FX-4300 in games that "technically" only use 3-4 cores, because these are module based chips, and as such, when the load is spread across 3-4 modules (instead of 2 modules) the CMT scaling losses are mitigated.
The performance improvement in that case is not because the game is magically using more cores, it is because the architecture has shared resources, and gives the highest per-thread performance when limited to 1 thread per core
module. When core-docking a pile-driver in order to achieve higher clocks, it really only "makes sense" to bother if you can disable 1 core per module, otherwise the gains from increased clock speed are likely to be lost to CMT scaling losses.Edited by mdocod - 3/7/14 at 9:44pm
