Core i7-6820HQ vs Core i5-8400H specs and performance

In our benchmarks, the Core i5-8400H beats the Core i7-6820HQ in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6820HQ in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i7-6820HQ has a slightly higher clock speed compared to 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 i7-6820HQ has more threads than cores. Each physical core is split into multiple threads.
