Intel’s Core i5-9400F is a hex-core 9th generation Coffee Lake desktop processor. It features base / boost clocks of 2.9 / 4.1 GHz, 9 MB of cache, a 65W TDP and it ships with a cooler but it does not have integrated graphics like the “non-F” variants. Although the 9400F is compatible with the enthusiast grade Z390 chipset it is normally paired with a better value for money B360 motherboard. At its launch the i5-9400F retailed for $180 but prices have dropped to the point ($135) that it now represents an excellent value proposition to gamers. Comparing the i5-9400F to the Ryzen 3600 shows that the 3600 is 8% better for quad-core processing but it costs 40% ($50) more than the 9400F. Ordinarily higher quad-core performance would result in better gaming but the Ryzen 3000 memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency. Gamers can invest the $50 savings in a better GPU, for example by upgrading from a 2060S to a 2070S. Since the GPU makes the most difference to gaming, the end result is a system which offers far superior real world gaming performance for similar money. For those gamers who demand the best of the best, it is necessary to jump to one of the higher frequency SKUs such as the 9600K but for everyone else the i5-9400F offers unparalleled value. [Aug '19 CPUPro]

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketing teams operate large numbers of reddit accounts. When UserBenchmark’s data contradicts their marketing spiel, they deflect by systematically attacking our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands make a large proportion lot of their profit from flagship hardware sales (4090, 14900KS, 7950X3D etc.). UserBenchmark's data helps consumers to choose hardware that offers similar real world performance at a fraction of the cost.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to make positive content about us. In addition, the brands with weaker products tend to spend more on youtube marketing, which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated reviews in an online community that's open and accessible to all. Looking at its 200+ UserBenchmark reviews, which are mostly written by virgin accounts, it is glaringly obvious that they were created by a marketing team. Real users don’t have any time or interest to promote one brand over another.
Why is UserBenchmark so popular with users?
Instead of trying to win lucrative sponsorship deals with billion dollar PC brands, we have spent the last 13 years 100% focussed on providing comprehensive, accurate and relevant information for our users. As a result, most of our users return over and over again because collectively they save millions of dollars every year.
