Intel Core i5-9600K vs Intel Core i7-9700

Core i5-9600K vs Core i7-9700 specs and performance

In our benchmarks, the Core i7-9700 beats the Core i5-9600K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9600K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-9700 has slightly more cores than the Core i5-9600K. Indeed, the Core i7-9700 has 8 cores compared to 6 cores found in the Core i5-9600K. It also has more threads than the Core i5-9600K. With our hardware info, we find that the Core i5-9600K has a slightly higher clock speed than the Core i7-9700. Despite this, the Core i7-9700 has a slightly higher turbo speed. The Core i7-9700 outputs less heat than Core i5-9600K thanks to a significantly lower TDP. 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 i7-9700 has slightly more L2 cache than the Core i5-9600K. The Core i7-9700 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 i5-9600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
