  • Good upgrade from a Core i3 8100
    Verified BuyerReviewed by rte24 - January 29, 2021

    Very good CPU and provides a good value for the last of the 1151 motherboards out there. Upgraded from a core i3 for a power user that could use more cores. The Dell Optiplex PC I put this in had an 8th gen Core i3 8100, and most boards that can use 8th gen Intel CPUs are compatible with 9th gen CPUs, too. Going from the i3 8100 and pairing the i5-9400 with faster 2666Mhz memory made a noticeable difference in performance. The current 10th gen i5 are also 6 core, but add hyperthreading for 12 threads. They require new motherboards to support socket 1200, though. This is a good way to breathe life into an older system.

  • Powerful processor
    Verified BuyerReviewed by tjbain - August 26, 2019

    This processor runs my 24/7 server. The server mainly handles media procurement and serving (via Plex). Thus far, nothing has slowed down the 9400. Plex routinely dishes out 2 streams of transcoded video (UHD graphics!!), and never needs to buffer or freeze. My only gripe with the processor is that it's a bit more power-hungry than my previous i5-6400t (which was specifically a low-power CPU)--but the difference equates to about $1 in power usage over the entire year. Soooo, in truth, that gripe is more about my nick-pickiness. If you're on the fence about this processor, I'm willing to bet that it'll work great for you regardless of the task. And at the price I paid for it, around $150 after rebates, it's hard NOT to recommend.

  • Great So Far!
    Verified BuyerReviewed by mrtyler95 - May 29, 2020

    The reason for my 4/5 star rating is because I haven’t had this processor for that long so I can’t give it an accurate long-term evaluation. But in the short time that I’ve had it, it has been great! I used the standard fan and thermal compound that came pre-installed and I have had any issues. The fan is very quiet and I don’t notice any sort of excess heat. Speeds are also very nice. I use my computer for music production; so I typically have many programs and VSTs running at one and I haven’t had any issues with running out of processing power.
