I like it so far!
At first I was thinking of getting the overclockable version, but coming from a potato laptop with a 4th gen i7 processor, I was okay with getting this version i5-8400, I like it, it's snappy fast, all works good so far, and i'm happy to say that, because I've never built a PC before and I just did 2 days ago by watching youtube tutorials lol, but I realized that if I wanted the i5-8600k I needed to get a more expensive motherboard, so I ended up saving lots of money to invest in the GPU and other peripherals. ----------------------------------------------------------------------------------------------------------------------------------------- UPDATE 2/25/2019 : After about a month of using my PC with this processor, I haven't had any issues with it! installed Extreme utility Tool for intel to verify the temps of the processor, Playing fornite after 1 - 3 hours, it has not exceeded more than 57 Degrees, so it was always pretty cool, I'm using the CPU cooler Deepcool Gammaxx 400 white LED. CPU usage never exceeded 75% I believe also while playing/rendering, used this processor with the Asus dual GTX 1060 6GB + 16GB 2400mhz Ram. For an 8 minute video in 1080p 60fps format, it took about 10-20 minutes of rendering ( of course load is both on the CPU and GPU during this process) , paired with the board : B360M DS3H + SSD Adata 240GB, the PC boots in 13-16 seconds from the moment I press the power on button on my computer. I am happy I went with this processor instead of the i3-8100 ( which I was thinking of at first ) but my friend suggested an i5 of the 8th gen at least for basic future proofing . ( BTW ) my YT channel is : Zealous Pumpkin check me out ! I do meme edits and funny videos about fortnite lol! ----------------------------------------------------------------------------------------------------------------------------------------- UPDATE 4/17/2019: 3 months in using this beautiful underrated CPU! This thing is really nice , For any interested gamer , Fortnite 1080p Maxed out an i5-8400 CPU + GTX 1060 6GB will play from 60-90fps , I cap my fps to 120 with my custom settings and with unlimited fps, it can reach 200fps+ sometimes and minimum 120. this processor with the right cooler, has never gone over 60C for me , and I live in quite a hot country btw. got this for 179.99$ before black friday and have never seen it go lower than that ( Just once on May-August 2018) for the same price but never again , so it was a great deal.

Was a great value and still is!
This CPU has offered great support and amazing value! I bought this in 2018 - it's end of 2025 now and I am still using it. I'm no longer gaming at the high end but for what I use my computer for most (low end gaming and watching youtube) this CPU has treated me great I really can't complain.

Very good value per core and a good, future-proof choice for gamers and majority of users.
Intel BX80684I58400 8th Gen Core i5-8400 Processor Please note that my mini-review is based on the limited in store testing, I am still waiting for my CPU to arrive so I can confirm the findings. To sum up, i5-8400 is currently the most affordable way to get a six core Intel build. It works out at $30 per core, which is even less than a cost per core of previous generation Kaby Lake CPUs. The downsides are - the multiplier overclocking is disabled and the base clock is pretty low, the TDP is limited to 65W. In practice what this means is a lot of benchmarks that can take advantage of 6 cores will look better than a 4-core CPU, but in single threaded tasks or some games, faster clocked cores can still give better responsiveness. The i5 8400 offers more than good enough performance for most tasks and uses very little power in idle and is still limited to around 65Watts under load. In my view this makes it a very good CPU choice for a main productivity/gaming machine that is powered on 24/7 or most of the day. The 6 cores future-proof the computer in case one suddenly wants to try their talents and a video game streamer or something similar. Paired with 370 chipset it also opens up a possibility of an upgrade, if someone really finds this CPU to be too limiting. Overall, I find this particular CPU to be of very good value currently and also offering enough performance for the majority of computing tasks - hence 5 stars.

nice cpu
it is easily installed. i used my old cooler master 212 evo on had a my 1155 socket cpu on it. i haven't pushed this cpu like i did my previous but it works well. the core temperature are in the high 3x and low 4x when boot from a cool state. but i haven't stressed it to see how high it will go. only game i played so far was rad rodgers and it handle that easily with a gtx 1060. will update review if necessary.

Great price for budget build, fast.
Product arrived quickly, installed easily. Make sure to have the arrow in the corner match your motherboard cpu mounts arrow, or you will damage the fragile pins. For those who don't know, 8400 means 8th gen where as a 7400 or 6400 means 7th gen 6th gen ect ect. MAKE SURE YOUR MOTHERBOARD IS COMPATIBLE WITH THE CPU, BEFORE PURCHASE. As for the performance of the cpu. It is very quick, plays all games on max settings with no issues at all, runs programs smoothly. Nice to have a good gaming pc after years of old and dusty computers and laptops. Keep your stuff clean and cool! No reason to spend 1000 dollars on these i7 or i9's. This is more than sufficient. Good luck people👍

It does support LGA1551 sockets
I have no problems with the CPU I’ve had for almost a month now it’s definitely budget friendly, it helped me on my motherboard that supports a LGA1151 socket I’m glad it could come with a stock cooler fan too. If you’re new to PC building this is ideally a good CPU for your setup it’s very underrated and I don’t see in the near future trying to replace this chip. You can’t overclock it it’s locked but really it’s worth the price and the performance it comes along with it.

Does what I need. Good processor.
I do a lot of demanding tasks with my home PC, and this i5 handles it all effortlessly. I have 8GB ram and an rtx 2060 video card. I can play all the next-gen games at 4k with reasonable frame rates. I also do game development and have YouTube running along with Unity editor and other programs. My system never seems to struggle with whatever I throw at it.

Desde marzo se me antojó cambiarme de componentes en mi ordenador. Tenía anteriormente: -CPU: Intel Core i5 4440 3.1GHz -GPU: Asus Strix RX 470 OC 4GB -Placa: Gigabyte B85M-D3H -RAM: 16GB DDR3 1866MHz -Fuente: Aerocool KCAS Bronze 600W Lo único que quería cambiar fue la CPU, la placa y la RAM. Ya que como mi anterior PC tenía Intel de 4ª generación, CPU de DDR3, y placa con socket de 1150. Para saltar a la nueva generación, tenía que cambiar la CPU, que además, había que cambiar la placa, y había que cambiar la RAM. Opté por el Intel Core i5 8400 de 2.8GHz, la RAM era Ballistix Sport LT de 16GB DDR4 de 2400MHz (8x2) y la placa era Gigabyte B360M-DS3H. Con todo esto, manteniendo la gráfica y la fuente de alimentación, obtuve unos mejores resultados tanto en embalaje de productos, como de calidad de estos mismos. Del i5 4440 al i5 8400 ha sido como un 30% o más de mejora, así como la mejora de la RAM al pasar de 1866MHz y DDR3 a los 2400MHz y DDR4. La CPU si bien a mí se me calentaba unas pocas veces debido a las múltiples tareas que hice los primeros días (instalar programas, juegos, etc), el rendimiento es indiscutible que es de calidad-precio. Por menos de 200 € tienes una buena CPU. Con respecto a los juegos, probando The Witcher III: Wild Hunt en Alto-Ultra mantuve alrededor de los 60 y los 75fps (activé la V-Sync porque el tearing del juego me molestaba, y mi monitor era de máximo 75Hz), y los resultados eran sobresalientes, sino que más destacables. Si queréis montaros un buen PC para jugar, el i5 8400 es una buena inversión para lo que vale, podéis jugar a prácticamente todo con este procesador. Se aprovechan muy bien los 6 núcleos y 6 hilos que tiene, con frecuencia de base de 2.8GHz y turbo de hasta 4.0GHz.

Estoy MUY SATISFECHO con este procesador! El desempeño es poco mejor que un core i7 7700k, que hasta el año pasado fué uno de los mejores de Intel. Además, el i5 8400 es mucho más barato y consume menos energía. Este procesador, de la mano con una buena tarjeta gráfica, te dejará correr cualquier juego con las opciones de gráficos al máximo. En la caja vienen el procesador y un ventilador de fábrica, el cual será suficiente ya que a este procesador no se le puede hacer overclocking. Es importante recordar que para usarlo es indispensable tener una tarjeta madre de serie 300 (busca que la tarjeta diga Z370, B360 o H310). No por nada es en procesador Coffee Lake mejor vendido.

Great CPU overall, six cores with an all core boost clock of 3.8 GHz makes it an amazing chip for more affordable gaming even with a more high end graphics card. I have it paired with a GTX 1070 for max. settings, 75Hz gaming at 1080p and this CPU handles it very well, reaching basically 100% GPU usage in most games (other than GTA V). The only problem so far is that in certain games, such as The Witcher 3, there is a fair bit of stuttering, although I'm almost certain that is down to the fact that I'm running a single 8GB stick of DDR4 memory, which I plan to add another stick to very soon to run in dual channel mode to reduce the CPU usage and stuttering as well as increase my FPS. The only other minor problem that I have had is with the stock cooler that Intel supplies, the problem that I have with it isn't with performance or noise, but with aesthetics, in my opinion it just doesn't look very nice in a windowed case which is why I replaced it with a Hyper 212X from Cooler Master, not only making my system look a lot nicer, but also dropping thermals whilst gaming by about 10C (roughly 65 to 55C). other than these two easily remedied problems that weren't even caused by the CPU itself, it is almost perfect and once I have upgraded to dual channel memory I think it will be even better delivering a smooth gaming experience even when paired with a GPU such as the GTX 1070.

Best processor for the budget gamers. You cannot overclock it but you don't have to overclock it. This processor can do everything. Runs on 3.8 GHz. Smooth as butter. I can stream any game with no lag or stutter. If you want to overclock your processor then go for the unlocked processors such as 8600k. But for me, this does the job without the need for overclocking it.
