Intel Core i5-9600KF vs Intel Core i7-8086K

Core i5-9600KF vs Core i7-8086K benchmarks

Our benchmark analysis concludes that the Core i7-8086K performs better than the Core i5-9600KF. Despite this, the Core i5-9600KF has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-8086K has more threads. These CPUs have different clock speeds. Indeed, the Core i7-8086K has a slightly higher clock speed compared to the Core i5-9600KF. Also, the Core i7-8086K 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Core i7-8086K also has slightly more L3 cache.

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. For instance, the Core i5-9600KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
