Overall however, the most important factor when it comes to the CPU's effect on game performance is that Intel Processors almost always perform better than AMD Processors. The main reason for this is because Intel's are more appropriately designed for running advanced computer softwares, whereas AMD's are more ideal for PC gaming. PCSX2 is definitely the former, since it is a complicated software that is meant to run Non-PC-formatted games. | Overall however, the most important factor when it comes to the CPU's effect on game performance is that Intel Processors almost always perform better than AMD Processors.

For comparison, AMD FX Processors (currently the most prominent/powerful series of AMD Processors) will not match the performance of the Intel i7 series.

An Intel i7-4770K 3.5 GHz will perform better than an AMD FX-9370 4.4 GHz, even though the FX-9370 has a much higher clock-rate. The main reason for this is because in the current AMD FX micro-architectures (Bulldozer and PileDriver), the number of Floating-Point Units is half the number of total CPU cores. This means that each unit is shared between two cores. If one core is currently using the FPU, the other core sharing it must wait to do the same. It is only free to perform integer operations. PCSX2 makes heavy use of floating-point. | ||
It is also important to note that having more than two cores does not increase the emulation performance of PCSX2. This is because PCSX2 currently uses only two cores, so having a greater number of CPU cores above two will not atone for a lower clock-rate. It can be improved by enabling the MTVU hack in the Speedhacks menu, but not by much. | It is also important to note that having more than two cores does not increase the emulation performance of PCSX2.
