Intel Core i5-9400F vs Intel Core i7-2700K

Core i5-9400F vs Core i7-2700K comparison

Our benchmark analysis concludes that the Core i5-9400F performs better than the Core i7-2700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-2700K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-9400F has significantly more cores than the Core i7-2700K. Indeed, the Core i5-9400F has 6 cores compared to 4 cores found in the Core i7-2700K. Despite this, the Core i7-2700K has more threads than the Core i5-9400F. With our hardware info, we find that the Core i7-2700K has a slightly higher clock speed than the Core i5-9400F. Despite this, the Core i5-9400F has a slightly higher turbo speed. A Core i5-9400F CPU outputs less heat than a Core i7-2700K CPU because of its 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 i5-9400F has the same number of threads as cores. This means the the CPU does not support hyperthreading.
