Intel Core i5-11600KF vs Intel Core i9-9900KF

Core i5-11600KF vs Core i9-9900KF specs and performance

According to the hardwareDB Benchmark tool, the Core i9-9900KF is faster than the Core i5-11600KF. Despite this, the Core i5-11600KF has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i9-9900KF has slightly more cores with 8 cores compared to the Core i5-11600KF that has 6 cores. It also has more threads than the Core i5-11600KF. With our hardware info, we find that the Core i5-11600KF has a slightly higher clock speed than the Core i9-9900KF. Despite this, the Core i9-9900KF has a slightly higher turbo speed. The Core i9-9900KF outputs less heat than Core i5-11600KF thanks to a slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-11600KF has significantly more L2 cache than the Core i9-9900KF. Despite this, the Core i9-9900KF has slightly more L3 cache compared to the Core i5-11600KF.

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 i5-11600KF has more threads than cores. Each physical core is split into multiple threads.
