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, they have a similar turbo frequency, that their respective TDP are of the same order. Both were produced in the same year.

Performances :


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


Cinebench R15 - Multi-thread & single thread score
Intel Core i9-10900KF#ad 225
2,658
Intel Core i9-10900K#ad 230
2,620


In single core, the difference is 2%. In multi-core, the difference in terms of gap is 1%.


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 i9-10900KF#ad 540
6,400
Intel Core i9-10900K#ad 530
6,160


In single core, the difference is 2%. In multi-core, the difference in terms of gap is 4%.


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 i9-10900K#ad 3,200
24,120
Intel Core i9-10900KF#ad 3,120
23,840


In single core, the difference is 3%. In multi-core, the differential gap is 1%.


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 64-bit:

Geekbench 4 - Multi-core & single core score - Windows 64-bit
Intel Core i9-10900K#ad 6,604
41,980
Intel Core i9-10900KF#ad 6,356
39,494


In single core, the difference is 4%. In multi-core, the differential gap is 6%.


Geekbench 4 is a complete benchmark platform with several types of tests, including data compression, images, AES encryption, SQL encoding, HTML, PDF file rendering, matrix computation, Fast Fourier Transform, 3D object simulation, photo editing, memory testing. This allows us to better visualize the respective power of these devices. For each result, we took an average of 250 values on the famous benchmark software.


On Windows:

Geekbench 5 - Multi-core & single core score - Windows
Intel Core i9-10900K#ad 1,434
