We can better compare what are the technical differences between the two processors. The processor Intel Core i7-11700K has more cores, the maximum frequency of Intel Core i7-11700K is greater, that the thermal dissipation power of Intel Core i5-9400H is less. The Intel Core i7-11700K was designed earlier.

Performances :


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


Cinebench R20 - Multi-thread & single thread score
Intel Core i7-11700K#ad 598
5,605
Intel Core i5-9400H#ad 437
1,812


In single core, the difference is 37%. In multi-core, the differential gap is 209%.


Cinebench R20 is a multi-platform test software which allows to evaluate the hardware capacities of a device such as a computer, a tablet, a server. This version of Cinebench takes into account recent developments in processors with multiple cores and the latest improvements in rendering techniques. The evaluation is ultimately even more relevant.


PassMark - CPU Mark & single thread
