Core i7-6820HQ vs Core i5-2500K comparison

According to the hardwareDB Benchmark tool, the Core i7-6820HQ is faster than the Core i5-2500K. Despite this, the Core i5-2500K has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core i7-6820HQ has more threads. With our hardware info, we find that the Core i5-2500K has a slightly higher clock speed than the Core i7-6820HQ. Also, the Core i5-2500K has a slightly higher turbo speed. A Core i7-6820HQ 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.

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 i7-6820HQ has more threads than cores. Each physical core is split into multiple threads.
