Core i5-11600KF vs Ryzen 9 6900HX benchmarks

According to the hardwareDB Benchmark tool, the Ryzen 9 6900HX 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 Ryzen 9 6900HX 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 Ryzen 9 6900HX. In addition, both chips have the same turbo speed. The Ryzen 9 6900HX outputs less heat than Core i5-11600KF thanks to a significantly 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 Ryzen 9 6900HX has slightly more L2 cache than the Core i5-11600KF. The Ryzen 9 6900HX also has slightly more L3 cache.

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.
