Core i7-2600K vs Core i7-3820QM specs and performance

According to the hardwareDB Benchmark tool, the Core i7-2600K is faster than the Core i7-3820QM. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-3820QM in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core i7-2600K has a slightly higher clock speed than the Core i7-3820QM. Also, the Core i7-2600K has a slightly higher turbo speed. The Core i7-3820QM outputs less heat than Core i7-2600K 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. Indeed, the Core i7-2600K has more threads than cores. Each physical core is split into multiple threads.
