Intel · Core i5 · 2019 · LGA1151
The Intel Core i5-9400F is a desktop processor with 6 cores, released in 2019 at an MSRP of $174. It is part of the Core i5 lineup, using the 9th Gen platform, and fits the LGA1151 socket. Internally, it is built on the "Coffee Lake Refresh" architecture. The Core i5-9400F has a base clock of 2.9 GHz and can boost up to 4.1 GHz depending on workload and thermal headroom. Intel manufactures the "Coffee Lake Refresh" silicon on a 14nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR4 memory. With a TDP of 65W, the Core i5-9400F is an efficient chip suitable for modest cooling solutions. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB/core of L1, 1.5MB of L2, and 9MB of L3 cache.
No integrated graphics — discrete GPU required. One of the most popular budget gaming CPUs of its generation, frequently recommended for its price-to-performance ratio.
