Intel Core i9-9900KF vs Intel Core i5-12600KF

Core i9-9900KF vs Core i5-12600KF benchmarks

Our benchmark analysis concludes that the Core i5-12600KF performs better than the Core i9-9900KF. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900KF in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-12600KF has slightly more cores with 10 cores compared to the Core i9-9900KF that has 8 cores. But they both have the same number of threads. With our hardware info, we find that the Core i5-12600KF has a slightly higher clock speed than the Core i9-9900KF. Despite this, the Core i9-9900KF has a slightly higher turbo speed. A Core i9-9900KF CPU outputs less heat than a Core i5-12600KF 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. Indeed, the Core i9-9900KF has more threads than cores. Each physical core is split into multiple threads.
