Intel Core i5-9600KF vs Intel Core i9-9880H

Core i5-9600KF vs Core i9-9880H specs and performance

Our benchmark analysis concludes that the Core i9-9880H performs better than the Core i5-9600KF. Despite this, the Core i5-9600KF has the advantage in our gaming benchmark.

With info from our database, we find that the Core i9-9880H 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. These CPUs have different clock speeds. Indeed, the Core i5-9600KF has a significantly higher clock speed compared to the Core i9-9880H. Despite this, the Core i9-9880H has a slightly higher turbo speed. The Core i9-9880H outputs less heat than Core i5-9600KF 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 Core i9-9880H has slightly more L2 cache than the Core i5-9600KF. The Core i9-9880H also has significantly 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. For instance, the Core i5-9600KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
