Intel Core i5-8365U vs Intel Core i5-2500K

Core i5-8365U vs Core i5-2500K specs and performance

Our benchmark analysis concludes that the Core i5-8365U performs better than the Core i5-2500K. Despite this, the Core i5-2500K has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i5-8365U has more threads. Our comparison shows that the Core i5-2500K has a significantly higher clock speed compared to the Core i5-8365U. Despite this, the Core i5-8365U has a slightly higher turbo speed. A Core i5-8365U 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 i5-8365U has more threads than cores. Each physical core is split into multiple threads.
