Product overview

Released in Q1 2019 as part of Intel’s 9th‑gen Core (Coffee Lake Refresh) lineup, the Core i5‑9400F is a 6‑core/6‑thread, 65 W desktop CPU for the LGA1151 (300‑series) platform. It runs at 2.9 GHz base with up to 4.1 GHz Turbo. The F‑suffix means there’s no integrated graphics, so a discrete GPU is required. It is now discontinued.

Positioned as a mainstream Core i5, it exists to offer a lower‑cost path to gaming and everyday workloads when overclocking and Hyper‑Threading aren’t priorities. With DDR4‑2666 support and a locked multiplier, it suits budget and midrange systems focused on 1080p gaming and office/productivity. Unique note: no iGPU (F‑suffix).
