Core i7-9700KF vs Core i9-9940X comparison

Our benchmark analysis concludes that the Core i9-9940X performs better than the Core i7-9700KF. Despite this, the Core i7-9700KF has the advantage in our gaming benchmark.

With info from our database, we find that the Core i9-9940X has significantly more cores with 14 cores whereas the Core i7-9700KF has 8 cores. It also has more threads than the Core i7-9700KF. Our comparison shows that the Core i7-9700KF has a slightly higher clock speed compared to the Core i9-9940X. Also, the Core i7-9700KF has a slightly higher turbo speed. A Core i7-9700KF CPU outputs less heat than a Core i9-9940X 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 i7-9700KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
