Core i5-7400 vs Core i7-6820HQ specs and performance

In our benchmarks, the Core i7-6820HQ beats the Core i5-7400 in overall performance. Despite this, the Core i5-7400 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i7-6820HQ has more threads. Our comparison shows that the Core i5-7400 has a slightly higher clock speed compared to the Core i7-6820HQ. Despite this, the Core i7-6820HQ has a slightly higher turbo speed. The Core i7-6820HQ outputs less heat than Core i5-7400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
