IntelCore i5-9400 Desktop Processor 6 Cores up to 4.1 GHz Turbo LGA1151 300 Series 65W Processors BX80684I59400

I have went with Intel the last several builds and you cannot go wrong. They are very robust and seem to go on and on. I like the onboard video also. I have used AMD and they are good too, but I believe Intel is superior definitely. All a matter of personal opinion I know, but I have sure had great luck with Intel processors. I bought the 9400. Good price and is definitely "Snappier" then i thought it would be. Performs well. Will clearly recommend.

Great CPU for the price, works well.

I bought this for my ASRock 310 mini pc since I wanted to run a server out of my home. I love the fact that there are integrated graphics. It is really fast. Seriously. This thing will probably last me for several years. At least in terms of server usage. Although I can't wait to try a ryzen processor, I have a feeling that Intel is going to stick around for the future of processors, given the fact how incredibly efficiency they are, even though they are on the 14nm node. Definite buy.

When paired with a good GPU/Good monitor you can get all the frames you need. Do everything you need from work to gaming to music to movies and more. Very easy install or upgrade for your current motherboard. Took me less than 5 minutes. Even thoe its not an unlocked CPU i still get 4Ghz of cpu power with intel boost. A very good buy.

The pc that I upgraded this to originally had a core i3. This was a great improvement for that particular pc. It was one of few options that was compatible with the motherboard on that PC. This core i5 is capable of doing "some" things. Light/medium music editing, light/medium video editing, "Some" games, depending on if you use the stock graphics or a separate graphics card) and of course your browsing and surfing. You're likely to purchase this if you bought a stock branded PC (hp, acer etc) from a retailer and you needed to upgrade to do a tad bit more functionality. So you will get an improvement but keep in mind that this is a 9th generation device. The current gen is 13. I personally wouldn't recommend this on a custom pc build or something that requires a lot of speed. There are better similarly priced options and better motherboards that support those options. One last thing that really bothered me with this core i5 is that the fan is extremely loud and it revs up randomly. The fan also doesn't have screws, it has those punch things which can be a bit finicky. If you can replace the fan with an inexpensive low noise version do so.

I made a new file server build and this keeps the cpu happy under heavy load. It's tall and wide so you're going to need plenty of space. Don't even think about putting it in a small rig. But if you want great cooling at a pretty good price, look no further.

It’s a good cpu I would recommend getting the new 10th gen version though because it has 6 more threads but this is a good cpu I have it paired with my rtx 2060 and it gets above 100 FPS on max settings 1080p on most games

I purchased this CPU for a new rackmount file server build. I was looking for something decently powerful to handle Plex transcoding yet something easily cooled in an airflow constrained case. My server has 8 hard drives in a hot-swap array which generate a decent amount of heat. I paired this CPU with a Noctua NH-L9i low-profile cooler and this keeps the CPU around 40-55C during normal operations. This CPU has been basically plug and play, not requiring any additional tweaks and has been running 24x7 in my server since installation.
