Intel Core i5-9600KF vs Intel Core i7-1265U

Core i5-9600KF vs Core i7-1265U specs and performance

In our benchmarks, the Core i7-1265U beats the Core i5-9600KF in overall performance. Despite this, the Core i5-9600KF has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i7-1265U has significantly more cores than the Core i5-9600KF. Indeed, the Core i7-1265U has 10 cores compared to 6 cores found in the Core i5-9600KF. 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 i7-1265U. Despite this, the Core i7-1265U has a slightly higher turbo speed. The Core i7-1265U 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. In terms of cache, the Core i7-1265U has significantly more L2 cache when compared to the Core i5-9600KF. The Core i7-1265U 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. For instance, the Core i5-9600KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
