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 AMD Ryzen 7 4800U 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

In single core, the difference is 26%. In multi-core, the differential gap is 74%.


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.


On Windows:
