Intel Core i5-8600K vs Intel Core i9-9900KF

Core i5-8600K vs Core i9-9900KF benchmarks

According to the hardwareDB Benchmark tool, the Core i9-9900KF is faster than the Core i5-8600K. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8600K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i9-9900KF has slightly more cores with 8 cores compared to the Core i5-8600K that has 6 cores. It also has more threads than the Core i5-8600K. According to our data, the Core i5-8600K and Core i9-9900KF have the same clock speed. Despite this, the Core i9-9900KF 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. The info from our database shows that the Core i9-9900KF has more L2 cache than the Core i5-8600K. The Core i9-9900KF also has significantly 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 i5-8600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
