i5-9400F

• The i5-9400F has higher Level 3 Cache. This is useful when you have substantial multiprocessing workloads, many computationally intense simultaneous processes. More likely on a server, less on a personally used computer for interactive desktop workloads.
• The i5-9400F has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
• 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.

i7-6700

• The i7-6700 has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
• 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.

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.

The processor Intel Core i5-9400F has more 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.

Performance comparison with the benchmarks:

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

	CPU-Z — Multi-thread & single thread score
Intel Core i5-9400F	443 2.525
Intel Core i7-6700	428 2.202

In single core, the difference is 4%. In multi-core, the differential gap is 15%.

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.
