Intel Core i5-8600K vs Intel Core i7-9700KF

Core i5-8600K vs Core i7-9700KF benchmarks

According to the hardwareDB Benchmark tool, the Core i7-9700KF 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.

With info from our database, we find that the Core i7-9700KF has slightly more cores with 8 cores whereas the Core i5-8600K has 6 cores. It also has more threads than the Core i5-8600K. According to our data, the Core i5-8600K and Core i7-9700KF have the same clock speed. Despite this, the Core i7-9700KF 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 cache sizes of these CPUs are different. Indeed, the Core i7-9700KF has slightly more L2 cache than the Core i5-8600K. The Core i7-9700KF also has slightly more L3 cache.

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. For instance, the Core i5-8600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
