Intel Core i7-6820HQ vs Intel Core i7-8665U

Core i7-6820HQ vs Core i7-8665U benchmarks

In our benchmarks, the Core i7-8665U 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. These CPUs have different clock speeds. Indeed, the Core i7-6820HQ has a slightly higher clock speed compared to 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 i7-6820HQ 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. Indeed, the Core i7-6820HQ has more threads than cores. Each physical core is split into multiple threads.
