Intel Core i7-9700K vs Intel Core i5-12400

Core i7-9700K vs Core i5-12400 comparison

Our benchmark analysis concludes that the Core i5-12400 performs better than the Core i7-9700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-9700K 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 i5-12400 that has 6 cores. Despite this, the Core i5-12400 has more threads than the Core i7-9700K. These CPUs have different clock speeds. Indeed, the Core i7-9700K has a significantly higher clock speed compared to the Core i5-12400. Also, the Core i7-9700K has a slightly higher turbo speed. The Core i5-12400 outputs less heat than Core i7-9700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i7-9700K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
