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

Core i9-9900K vs Core i5-12600KF comparison

In our benchmarks, the Core i5-12600KF beats the Core i9-9900K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900K in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-12600KF has slightly more cores than the Core i9-9900K. Indeed, the Core i5-12600KF has 10 cores compared to 8 cores found in the Core i9-9900K. But they both have the same number of threads. Our comparison shows that the Core i5-12600KF has a slightly higher clock speed compared to the Core i9-9900K. Despite this, the Core i9-9900K has a slightly higher turbo speed. A Core i9-9900K 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.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i9-9900K has more threads than cores. Each physical core is split into multiple threads.
