FX-8120 vs Core i5-2500K specs and performance

Our benchmark analysis concludes that the Core i5-2500K performs better than the FX-8120. Furthermore, our gaming benchmark shows that it also outperforms the FX-8120 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the FX-8120 has more threads. These CPUs have different clock speeds. Indeed, the Core i5-2500K has a slightly higher clock speed compared to the FX-8120. The Core i5-2500K outputs less heat than FX-8120 thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the FX-8120 has more threads than cores. Each physical core is split into multiple threads.
