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 PDT of Intel Core i9-11900K is lower. 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
Intel Core i7-9800X#ad 547
5,401


In single core, the difference is 29%. In multi-core, the differential gap is 19%.


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
Intel Core i7-9800X#ad 171
1,692


In single core, the difference is 43%. In multi-core, the differential gap is 26%.


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.


PassMark - CPU Mark & single thread
Intel Core i9-11900K#ad 3,754
28,072
Intel Core i7-9800X#ad 2,580
18,170


In single core, the difference is 46%. In multi-core, the differential gap is 54%.


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.
