Core i5-2500K vs Ryzen 9 7900X comparison

Our benchmark analysis concludes that the Ryzen 9 7900X performs better than the Core i5-2500K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-2500K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Ryzen 9 7900X has significantly more cores with 12 cores compared to the Core i5-2500K that has 4 cores. It also has more threads than the Core i5-2500K. Our comparison shows that the Ryzen 9 7900X has a slightly higher clock speed compared to the Core i5-2500K. Also, the Ryzen 9 7900X has a significantly higher turbo speed. A Core i5-2500K CPU outputs less heat than a Ryzen 9 7900X CPU because of its 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.
