Intel Core i5-6600K vs Intel Core i5-2500K

Core i5-6600K vs Core i5-2500K comparison

According to the hardwareDB Benchmark tool, the Core i5-6600K is faster 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 these CPUs we notice that they have the same number of cores and the same number of threads. Our comparison shows that the Core i5-6600K has a slightly higher clock speed compared to the Core i5-2500K. Also, the Core i5-6600K has a slightly higher turbo speed. A Core i5-6600K CPU outputs less heat than a Core i5-2500K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-6600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
