Technically, the Core i9-9400F is based on the same semiconductor foundation as the past-generation Core i9-8400 Coffee Lake processors, differing only by a slightly increased clock frequency and the fact that the integrated GPU is hardware-locked at the production stage. Thus, the company has achieved a reduction in waste in the workplace, and left customers in the cold. However, due to the lack of shortage of these processors, the price for them usually does not exceed the recommended one, thereby making them, in some cases, profitable for purchase, in particular, when purchased from the computeruniverse.net online store.
In terms of performance in applications this is not best processor, however, in games it is better than a half times more expensive flagship Ryzen 7 2700X, which makes its choice very rational for mid-level gaming systems.

The new processor model from Intel was released as a result of production optimization. Intel Core i5-9400F is a processor with a disabled graphics core. Through the use of defective processors, the company in one fell swoop significantly reduced waste and increased the production of suitable products, and the buyer received the processors at a slightly more favorable price, but without integrated graphics.
AMD, in the same price category releases six-core Ryzen 5 processors, which, unlike the Core i5 series, have multi-threading support (SMT) and are the best option for “basic” configurations in terms of price / performance ratio. In addition, officially Coffee Lake Refresh continues to focus on dual-channel DDR4-2666 memory, while AMD repeatedly adds support for its processors to higher speeds, reaching the latest versions of mobile Raven Ridge to DDR4-3200.
Compared to last year’s Core i5-8400, in the new model the differences only in increasing in clock frequency of 100 MHz. The company also announced an improved internal thermal interface in the form of a highly efficient flux-free solder, but as it turned out, this applies only to other series products. In Intel Core i5-9400F, crystal soldering is not applied to the heat-spreading lid, and the internal thermal interface is exactly the same polymeric thermal paste used in the old Coffee Lake processors.

Testing and overclocking
Core i5-9400F can not be overclocked. And at the most, what the processor is capable for is working at the maximum allowed frequency within the Turbo Boost 2.0 technology.
|Nominal frequency||Maximum frequency Turbo Boost 2.0|
|1 core||2 cores||3 cores||4 cores||5 cores||6 cores|
|Core i5-8400||2,8 Ghz||4,0 Ghz||3,9 Ghz||3,9 Ghz||3,9 Ghz||3,8 Ghz||3,8 Ghz|
|Core i5-8500||3,0 Ghz||4,1 Ghz||4,0 Ghz||4,0 Ghz||4,0 Ghz||3,9 Ghz||3,9 Ghz|
|Core i5-9400(F)||2,9 Ghz||4,1 Ghz||4,0 Ghz||4,0 Ghz||4,0 Ghz||3,9 Ghz||3,9 Ghz|
According to performance tests in applications, it is clear that even slightly more affordable AMD six-cores can offer noticeably better performance due to the virtual multithreading of SMT.
Testing was conducted in applications Adobe Photoshop Lightroom Classic SS 8.1, Adobe Premiere Pro CC 2019 13.0, Blender 2.79b, Corona 1.3, Microsoft Visual Studio 2017 (15.9.9), OBS Studio 23.0.2, Stockfish 10, x264 r2851, x265 3.0+ 14 8bpp. The rendering speed for creating three-dimensional graphics, photo processing, video, video transcoding, compilation, archiving, computing chess moves were tested.
In gaming tests, the processor performs much better than its counterparts. Its better then a half times more expensive flagship Ryzen 7 2700X in gaming performance, which makes it a very rational choice for mid-level gaming systems.
All games in 1080p resolution (FullHD) and 1440p from the tests the processor perfectly runs if there are no applications running in the background: Assassin’s Creed Odyssey, Ashes of Singularity, Civilization VI: Gathering Storm, Far Cry New Dawn, Kingdom Come: Deliverance, Metro Exodus, Shadow of the Tomb Raider, Total War: Warhammer II, Watch Dogs 2.
A source of tests is 3dnews.ru.
According to customer reviews, the processor outperforms most AMD Ryzen 5-7 series processors in games up to 30fps +. Those who say 2-3 fps lie godlessly). Only in the Witcher Ryazan and intel go to the level. In the rest intel breaks.
As the disadvantages of the processor users have called the lack of any reserve for the future, and in this regard, AMD Ryzen processors are in one step ahead. Some of the buyers paid attention to the temperature that “jumps on the core:, which, according to Intel support, is the normal working process. A minor disadvantage is an imperfect boxed cooler that is quite noisy and is suitable only for the first time of using.
In general, customers in their reviews agreed that the Intel Core i5-9400F is one of the best options for a budget gaming PC for its price. The processor shows an average of 10% -15% weaker than 9600k, but it is 40% cheaper.
Worked fine out of the box.

Installed and works fine with no problems. Value is better than anything local I could find. Turbos up to 4 Ghz during gaming and works great. I’m not an overclocker so my review doesn’t cover that aspect. Worked fine with my new motherboard and memory. Wish all my builds had been this easy.

Great 6 core CPU for gaming!

You save around $100 by going with this processor vs i5-9600k. This i5-9400F is locked and cannot be overclocked. It runs at 2.9ghz and throttles up to 4.0. So far I love it but the overclocking demon in me wishes I would have spent more. When in actuality this CPU rocks and does everything I throw at it with ease. I paired mine with a Gigabyte Z390 UD and some 3200 MHz DDR4 thus speeding up my memory bus! Added an XFX RX580 graphics card and gaming is beautiful! $100 saved will mostly pay for your memory or an SSD or even your liquid cooler that by the way doesn’t have to be a double-wide radiator because this CPU is rated at only 65 watts it runs cool so I went with a single radiator and all runs very cool, so if on a budget this CPU is the way to go!
