Core i5-9600KF vs Core i7-7820X comparison

In our benchmarks, the Core i7-7820X beats the Core i5-9600KF in overall performance. Despite this, the Core i5-9600KF has the advantage in our gaming benchmark.

With info from our database, we find that the Core i7-7820X has slightly more cores with 8 cores whereas the Core i5-9600KF has 6 cores. It also has more threads than the Core i5-9600KF. Our comparison shows that the Core i5-9600KF has a slightly higher clock speed compared to the Core i7-7820X. Also, the Core i5-9600KF has a slightly higher turbo speed. A Core i5-9600KF CPU outputs less heat than a Core i7-7820X 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 i5-9600KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
