Price: prices can change over time. For technical reasons, they are not updated in real time. This is only an average of the results on the first page of each product, whether new or used. Shipping costs have not been integrated. To know the final price of the product, please go to the form of the shop. If no price is indicated, it means that we did not find any offers during the last update.

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.

Ratios: we first consider the average for the new price if available, the average for the used price otherwise. Performance / global cost ratio: This is the ratio of performance on Geekbench 4, divided by the cost of the product + the cost of electricity over 5 years for a duration of use of 13 hours per day.

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 225
Intel Core i9-10900K 230

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 540
Intel Core i9-10900K 530

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 3,200
Intel Core i9-10900KF 3,120

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 6,604
Intel Core i9-10900KF 6,356

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 1,434
Intel Core i9-10900KF 1,411

In single core, the difference is 2%. In multi-core, the differential gap is 3%.

On macOS:

Geekbench 5 - Multi-core & single core score - macOS
Intel Core i9-10900KF 1,324
Intel Core i9-10900K 1,296

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

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.
