Intel Core i5-6400 vs Intel Core i7-7700HQ

Core i5-6400 vs Core i7-7700HQ specs and performance

Our benchmark analysis concludes that the Core i7-7700HQ performs better than the Core i5-6400. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6400 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-7700HQ has more threads. These CPUs have different clock speeds. Indeed, the Core i7-7700HQ has a slightly higher clock speed compared to the Core i5-6400. Also, the Core i7-7700HQ has a slightly higher turbo speed. The Core i7-7700HQ 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.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
