We can better compare what are the technical differences between the two processors. The processor Intel Core i9-11900K has more cores, the maximum frequency of Intel Core i9-11900K is greater, that the thermal dissipation power of Intel Core i7-9750H 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
Intel Core i7-9750H#ad	462 3,492

In single core, the difference is 53%. In multi-core, the differential gap is 85%.

average of the performances got with these processors, you may get different results.

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 i7-9750H#ad	180 1,180

In single core, the difference is 36%. In multi-core, the differential gap is 81%.

average of the performances got with these processors, you may get different results.

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
Intel Core i7-9750H#ad	440 2,970

In single core, the difference is 37%. In multi-core, the differential gap is 94%.

average of the performances got with these processors, you may get different results.

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
Intel Core i7-9750H#ad	2,530 11,530

In single core, the difference is 48%. In multi-core, the differential gap is 143%.

Note: Commissions may be earned from the links above. These scores are only an
average of the performances got with these processors, you may get different results.

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.
