Intel Core i7-7820HQ vs Intel Core i5-2500K

Core i7-7820HQ vs Core i5-2500K comparison

Our benchmark analysis concludes that the Core i7-7820HQ 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.

Info from our database shows that they both have the same core count but the Core i7-7820HQ has more threads. These CPUs have different clock speeds. Indeed, the Core i5-2500K has a slightly higher clock speed compared to the Core i7-7820HQ. Despite this, the Core i7-7820HQ has a slightly higher turbo speed. A Core i7-7820HQ 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 i7-7820HQ has more threads than cores. Each physical core is split into multiple threads.
