Core i5-6400 vs Core i7-6820HQ specs and performance

Our benchmark analysis concludes that the Core i7-6820HQ performs better than the Core i5-6400. Despite this, the Core i5-6400 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-6820HQ has more threads. According to our data, the Core i5-6400 and Core i7-6820HQ have the same clock speed. Despite this, the Core i7-6820HQ has a slightly higher turbo speed. The Core i7-6820HQ outputs less heat than Core i5-6400 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 i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
