i5-9400F

• For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
• The i5-9400F has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present. It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.

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 i5-9400F is greater, that their respective TDP are of the same order. The Intel Core i5-9400F 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 i5-8400	442 2.666
Intel Core i5-9400F	443 2.525

In single core, the difference is 0%. In multi-core, the difference in terms of gap is 6%.

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.

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 i5-9400F	177 987
Intel Core i5-8400	169 954

In single core, the difference is 5%. In multi-core, the differential gap is 3%.

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.

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 R23 — Multi-thread & single thread score
Intel Core i5-8400	1.017 5.839

In single core, the difference is 1%. In multi-core, the difference in terms of gap is 5%.

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.

Cinebench R23 is cross-platform testing software that allows you to assess the hardware capabilities of a device such as a computer, tablet, 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. The test scene contains no less than 2,000 objects and more than 300,000 polygons in total.













	PassMark — CPU Mark & single thread
Intel Core i5-9400F	2.470 9.536
Intel Core i5-8400	2.401 9.206

In single core, the difference is 3%. In multi-core, the differential gap is 4%.

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.
