Intel Core i5-9400 vs Intel Core i7-7700HQ

Core i5-9400 vs Core i7-7700HQ comparison

Our benchmark analysis concludes that the Core i5-9400 performs better than the Core i7-7700HQ. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7700HQ in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-9400 has significantly more cores with 6 cores compared to the Core i7-7700HQ that has 4 cores. Despite this, the Core i7-7700HQ has more threads than the Core i5-9400. These CPUs have different clock speeds. Indeed, the Core i5-9400 has a slightly higher clock speed compared to the Core i7-7700HQ. Also, the Core i5-9400 has a slightly higher turbo speed. The Core i7-7700HQ outputs less heat than Core i5-9400 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 i5-9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
