Intel Core i7-8700K vs Intel Core i7-9700F

Core i7-8700K vs Core i7-9700F specs and performance

In our benchmarks, the Core i7-9700F beats the Core i7-8700K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-8700K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-9700F has slightly more cores with 8 cores compared to the Core i7-8700K that has 6 cores. Despite this, the Core i7-8700K has more threads than the Core i7-9700F. Our comparison shows that the Core i7-8700K has a slightly higher clock speed compared to the Core i7-9700F. Furthermore, both these CPUs have identical turbo speeds. The Core i7-9700F outputs less heat than Core i7-8700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i7-9700F has slightly more L2 cache when compared to the Core i7-8700K. However, both these chips have the same amount of 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. Indeed, the Core i7-8700K has more threads than cores. Each physical core is split into multiple threads.
