Core i5-2500K vs Pentium Gold G6405 specs and performance

Our benchmark analysis concludes that the Core i5-2500K performs better than the Pentium Gold G6405. Furthermore, our gaming benchmark shows that it also outperforms the Pentium Gold G6405 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-2500K has significantly more cores with 4 cores compared to the Pentium Gold G6405 that has 2 cores. But they both have the same number of threads. Our comparison shows that the Pentium Gold G6405 has a slightly higher clock speed compared to the Core i5-2500K. The Pentium Gold G6405 outputs less heat than Core i5-2500K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-2500K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
