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

Core i5-8600K vs Core i7-9700K specs and performance

Our benchmark analysis concludes that the Core i7-9700K performs better 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 i7-9700K 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 i7-9700K have the same clock speed. Despite this, the Core i7-9700K 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 i7-9700K has more L2 cache than the Core i5-8600K. The Core i7-9700K 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.
