We can better compare what are the technical differences between the two processors. We see that the two processors have an equivalent number of cores, the maximum frequency of Intel Core i9-11900K is greater, that the thermal dissipation power of Intel Core i7-9700KF is less. The Intel Core i9-11900K was designed earlier.

Performances :


Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.


CPU-Z - Multi-thread & single thread score

6,443
Intel Core i7-9700KF#ad 526
3,881


In single core, the difference is 35%. In multi-core, the differential gap is 66%.


CPU-Z is a system information software that provides the name of the processor, its model number, the codename, the cache levels, the package, the process. It can also gives data about the mainboard, the memory. It makes real time measurement, with finally a benchmark for the single thread, as well as for the multi thread.


PassMark - CPU Mark & single thread
