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, the maximum frequency of Intel Core i9-11900F is greater, that the thermal dissipation power of AMD Ryzen 9 5900HX is less. 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.

PassMark - CPU Mark & single thread
AMD Ryzen 9 5900HX#ad 3,297
Intel Core i9-11900F#ad 3,571

In single core, the difference is 8%. In multi-core, the difference in terms of gap is 4%.

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 i9-11900F#ad 7,193
AMD Ryzen 9 5900HX#ad 6,195

In single core, the difference is 16%. In multi-core, the differential gap is 5%.

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 i9-11900F#ad 1,706
AMD Ryzen 9 5900HX#ad 1,465

In single core, the difference is 16%. In multi-core, the differential gap is 23%.

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.
