Intel Core i5-8400 vs Intel Core i7-6920HQ

Core i5-8400 vs Core i7-6920HQ specs and performance

In our benchmarks, the Core i5-8400 beats the Core i7-6920HQ in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6920HQ in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-8400 has significantly more cores than the Core i7-6920HQ. Indeed, the Core i5-8400 has 6 cores compared to 4 cores found in the Core i7-6920HQ. Despite this, the Core i7-6920HQ has more threads than the Core i5-8400. Our comparison shows that the Core i7-6920HQ has a slightly higher clock speed compared to the Core i5-8400. Despite this, the Core i5-8400 has a slightly higher turbo speed. The Core i7-6920HQ outputs less heat than Core i5-8400 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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
