Intel Core i5-2500K vs Intel Core i7-2820QM

Core i5-2500K vs Core i7-2820QM specs and performance

Our benchmark analysis concludes that the Core i5-2500K performs better than the Core i7-2820QM. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2820QM in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i7-2820QM has more threads. These CPUs have different clock speeds. Indeed, the Core i5-2500K has a significantly higher clock speed compared to the Core i7-2820QM. Also, the Core i5-2500K has a slightly higher turbo speed. The Core i7-2820QM outputs less heat than Core i5-2500K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i5-2500K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
