Product overview
Launched in Q1 2019, the Core i5-9400 is a 9th‑generation Intel Core desktop CPU (Coffee Lake) for LGA1151 systems using 300‑series chipsets. It features 6 cores and 6 threads, a 2.9 GHz base clock with up to 4.1 GHz turbo, 9 MB cache, a 65 W TDP, DDR4‑2666 support, and integrated Intel UHD Graphics 630.
Positioned as a mainstream i5, it exists to power mid‑range gaming and everyday rigs without overclocking; as a non‑K part it has a locked multiplier. It’s well‑suited to 1080p gaming with a discrete GPU, office/productivity work, and budget builds that can use the iGPU for display and troubleshooting. The Core i5‑9400 is now discontinued according to Intel’s product page.
