Intel Core i5-8400 vs Intel Core i7-9700K

Core i5-8400 vs Core i7-9700K comparison

In our benchmarks, the Core i7-9700K beats the Core i5-8400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8400 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i7-9700K has slightly more cores than the Core i5-8400. Indeed, the Core i7-9700K has 8 cores compared to 6 cores found in the Core i5-8400. It also has more threads than the Core i5-8400. These CPUs have different clock speeds. Indeed, the Core i7-9700K has a slightly higher clock speed compared to the Core i5-8400. Also, the Core i7-9700K has a slightly higher turbo speed. A Core i5-8400 CPU outputs less heat than a Core i7-9700K CPU because of its significantly lower TDP. 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 i5-8400. The Core i7-9700K also has slightly more L3 cache.

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 i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
