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 4800H 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
Intel Core i9-11900K#ad 708
6,443
AMD Ryzen 7 4800H#ad 518
5,577


In single core, the difference is 37%. In multi-core, the differential gap is 16%.


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.


Cinebench R15 - Multi-thread & single thread score
Intel Core i9-11900K#ad 245
2,140
AMD Ryzen 7 4800H#ad 190
1,850


In single core, the difference is 29%. In multi-core, the differential gap is 16%.


Cinebench R15 evaluates the performance of CPU calculations by restoring a photorealistic 3D scene. The scene has 2,000 objects, 300,000 polygons, uses sharp and fuzzy reflections, bright areas, shadows, procedural shaders, antialiasing, and so on. The faster the rendering of the scene is created, the more powerful the PC is, with a high number of points.


Cinebench R20 - Multi-thread & single thread score
Intel Core i9-11900K#ad 604
5,748
AMD Ryzen 7 4800H#ad 470
4,240


In single core, the difference is 29%. In multi-core, the differential gap is 36%.


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
Intel Core i9-11900K#ad 3,754
28,072
AMD Ryzen 7 4800H#ad 2,680
19,370


In single core, the difference is 40%. In multi-core, the differential gap is 45%.


PassMark is a benchmarking software that performs several performance tests including prime numbers, integers, floating point, compression, physics, extended instructions, encoding, sorting. The higher the score is, the higher is the device capacity.


On Windows:

Geekbench 5 - Multi-core & single core score - Windows
Intel Core i9-11900K#ad 1,808

AMD Ryzen 7 4800H#ad 1,180
7,397


In single core, the difference is 53%. In multi-core, the differential gap is 34%.


Geekbench 5 is a software for measuring the performance of a computer system, for fixed devices, mobile devices, servers. This platform makes it possible to better compare the power of the CPU, the computing power and to compare it with similar or totally different systems. Geekbench 5 includes new workloads that represent work tasks and applications that we can find in reality.
