Core i5 9400F is an intermediate processor from Intel ‘s ninth generation . The model promises good performance to run games and productivity applications, offering speeds between 2.9 and 4.1 GHz. The component has six cores and can be found for at least $157.00, being an interesting cost-effective option. benefit. Despite this, the CPU does not have an integrated graphics solution, which can be useful when building a more affordable PC . Check below for more details on the Intel chip and find out if it is a good option for you.


The Intel Core i5 9400F Review is a hexa-core without Hyper-Threading technology. So there are six physical cores and the same six threads. The product clock can reach 4.1 GHz, and overclocking is not supported. The CPU was developed in a 14 nm manufacturing process, which should guarantee a good part of Intel’s new technologies, as well as a good relationship between consumption and performance.

Whether in productivity or in games, the processor promises to offer adequate performance, being able to reproduce more demanding professional software and also current games. Its performance when running games will also depend on the dedicated GPU used in the system. The 4.1 GHz turbo clock, in turn, is within the standards of intermediate processors and, even though it is the maximum offered, it should be enough to meet several different types of use.

Modern processors try to be more efficient. Thus, most of the intermediate models from Intel work with 65 Watt TDP, like the Intel Core i5 9400F. This number, combined with the overclocking block, makes the heat generated by the component easily dissipated by even the most modest thermal solutions. This is because the chip itself must perform an intelligent control of the frequencies and, consequently, deliver a lower consumption.

The LGA1151 socket used in the Intel processor has several chipsets, which means that processors can have a wide variety of motherboards aimed at different segments. The H110, for example, is an entry-level model, that is, it does not normally support technologies such as Intel Optane memories, for example. Despite this, it can be found at lower prices, with plates starting at R $ 320.

The Z270 chipset, on the other hand, offers a greater variety of features, with components that, in addition to delivering more performance, also bring a bolder design and construction that promises greater durability. Plates with the model appear on the Brazilian market for average prices of R $ 700.


The main competitor of the Intel Core i5 9400F is the AMD Ryzen 5 2600. The AMD chip offers six cores and 12 threads, with frequencies between 3.4 and 3.9 GHz. There is also the possibility of overclocking, which can give a certain advantage to the rival model. The Ryzen 5 2600 also uses socket AM4, which makes the product compatible with most motherboards for the brand’s processors. These CPUs require only the updated BIOS to support all components of the Ryzen family.


Costing from R $ 685 in Brazil, according to the official website of Intel, the Core i5 9400F should please most users due to its cost-effective profile. Despite this, it is necessary to consider the need to install a dedicated video card, as there is no integrated graphics solution in the product. And the good CPU performance to run more demanding games and applications, in turn, depends on the presence of a good GPU installed in the system.

Another factor that favors the Intel product, is that the ninth generation Core i7 processor is on sale in Brazil for almost twice its price. Therefore, the Core i5 is an even more interesting option for those looking to pay less when building their PC. But, it is worth the tip: there are competing options that can also be interesting, costing more or less the same thing and coming with good offers of resources.


1.Recent technology

As it is a ninth generation processor, the Intel Core i5 9400F has the main features and technologies added to the 14 nm generation. Thus, the processor promises to be extremely efficient. Bringing up-to-date hardware is also important in relation to the work of each core, which is exploited in a more appropriate way. Therefore, the chip must be more stable and able to be used with modern software that can benefit from the number of threads available.

2. Low price compared to the ninth generation

The Intel Core i5 9400F also stands out due to the price, since, when compared to other ninth generation models, it can be considered more affordable. Even compared to the predecessor Intel Core i5 8400, the latest chip promises better value for money.

At least in the Brazilian market, the model positions itself with a value that is not far above entry-level models, as is the case with the Intel Core i3 9100F. In addition, the processor is much cheaper compared to Core i7 9700K, and Core i9 9900K, premium components of the same generation.


Whether for games or productivity, the six cores and six threads of the Intel Core i5 9400F, should offer enough performance to deliver high frame rates for games. The chip also promises to be interesting to run heavy software properly, being interesting for users working with video editing, for example.

4.Low energy consumption

The TDP of only 65 Watts, is another differential of the processor, which, despite the low energy consumption, promises to offer enough performance to explore the potential of the dedicated graphics card. Low energy consumption also means that the processor can be used in systems with more modest thermal solutions, making it possible to install the processor even in cases without much space.


1.No integrated graphics solution

Intel “F” processors do not have an integrated graphics solution, requiring users to invest in a dedicated graphics card. And, to have a GPU suited to the performance of the Core i5 9400F, the investment can be high. Therefore, Intel chips with this feature may end up lagging behind AMD competitors , such as the Ryzen 2200G and 3200G . Both have their own graphics and good performance, featuring Vega architecture .

2.No multithreaded

The Intel Core i5 9400F also lacks Intel’s Hyper Threading technology , which is equivalent to AMD’s SMT. This technology allows each physical core to work on two fronts as if they were two logical cores. Again, comparing the model to a competitor in the same price range, there is a disadvantage.

The Ryzen 5 2600, for example, features six cores and 12 threads, with a similar clock and also without integrated video. AMD’s processor promises even more performance, especially in applications that benefit from more cores.

3.Blocked for overclocking

Another point that may disappoint on the ninth generation Core i5 is the overclocking block. This practice forces the chip to work at even higher frequencies, thus delivering greater performance. To access this feature on Intel processors, it is necessary to resort to the K line, which is much more expensive compared to the “F” models. The competition (in this case, AMD), for example, has CPUs unlocked even in input components.

4. Platform does not favor upgrade

Socket 1151 has been used since the sixth generation of Intel processors. But the eighth and ninth generation processors cannot be used on motherboards intended for the sixth and seventh generation models, although the socket is compatible. This constant change in socket patterns ends up hindering users who have older processors – in addition to the uncertainty about new lithographs in the future. AMD, for example, uses the same AM4 socket on Ryzen, with only a BIOS update sufficient to make older motherboards compatible.
