Intel Core i5-6440HQ vs Intel Core i7-8665U

Core i5-6440HQ vs Core i7-8665U benchmarks

In our benchmarks, the Core i7-8665U beats the Core i5-6440HQ in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-6440HQ in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i7-8665U has more threads. With our hardware info, we find that the Core i5-6440HQ has a slightly higher clock speed than the Core i7-8665U. Despite this, the Core i7-8665U has a slightly higher turbo speed. The Core i7-8665U outputs less heat than Core i5-6440HQ 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 i5-6440HQ has the same number of threads as cores. This means the the CPU does not support hyperthreading.
