Core i7-8086K vs Core i9-11900H comparison

According to the hardwareDB Benchmark tool, the Core i7-8086K is faster than the Core i9-11900H. Despite this, the Core i9-11900H has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i9-11900H has slightly more cores with 8 cores compared to the Core i7-8086K that has 6 cores. It also has more threads than the Core i7-8086K. Our comparison shows that the Core i7-8086K has a significantly higher clock speed compared to the Core i9-11900H. Also, the Core i7-8086K has a slightly higher turbo speed. The Core i9-11900H outputs less heat than Core i7-8086K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i7-8086K has more threads than cores. Each physical core is split into multiple threads.
