Core i5-8250U vs Core i5-2500K comparison

Our benchmark analysis concludes that the Core i5-2500K performs better than the Core i5-8250U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8250U in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i5-8250U has more threads. Our comparison shows that the Core i5-2500K has a significantly higher clock speed compared to the Core i5-8250U. Also, the Core i5-2500K has a slightly higher turbo speed. A Core i5-8250U CPU outputs less heat than a Core i5-2500K CPU because of its significantly 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. Indeed, the Core i5-8250U has more threads than cores. Each physical core is split into multiple threads.
