Intel Core i5-9600KF vs Intel Core i7-8700K

Core i5-9600KF vs Core i7-8700K comparison

In our benchmarks, the Core i7-8700K beats the Core i5-9600KF in overall performance. 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 i7-8700K has more threads. Both the Core i5-9600KF and Core i7-8700K have the same clock speed. Despite this, the Core i7-8700K 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 i7-8700K also has slightly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-9600KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
