We can better compare what are the technical differences between the two processors.

Suggested PSU: We assume that we have An ATX computer case, a high end graphics card, 16GB RAM, a 512GB SSD, a 1TB HDD hard drive, a Blu-Ray drive. We will have to rely on a more powerful power supply if we want to have several graphics cards, several monitors, more memory, etc.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

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.

CPU-Z - Multi-thread & single thread score
Intel Core i9-10900KF#ad 643
Intel Core i9-10900K#ad 577

In single core, the difference is 11%. In multi-core, the difference in terms of gap is 13%.

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 i9-10900KF#ad 225
Intel Core i9-10900K#ad 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#ad 540
Intel Core i9-10900K#ad 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#ad 3,200
Intel Core i9-10900KF#ad 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#ad 6,604
Intel Core i9-10900KF#ad 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#ad 1,434
Intel Core i9-10900KF#ad 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#ad 1,324
Intel Core i9-10900K#ad 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.
