Core i7-7700HQ vs Core i5-8400H benchmarks

In our benchmarks, the Core i5-8400H beats the Core i7-7700HQ in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7700HQ in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core i7-7700HQ has a slightly higher clock speed than the Core i5-8400H. Despite this, the Core i5-8400H has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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. Indeed, the Core i7-7700HQ has more threads than cores. Each physical core is split into multiple threads.
