AMD Ryzen 5 8400F 6-Core AM5 Processor - 4.7GHz, 65W
The AMD Ryzen 5 8400F 6-Core AM5 Processor is built for PC builders who want capable gaming and content-creation performance within a sensible power budget. Its six cores and twelve threads handle demanding workloads — from AAA gaming to video editing — while the Zen 4 architecture and 4nm process node keep efficiency high. It ships with a Wraith Stealth cooler and supports overclocking, making it a straightforward choice for AM5 platform builds.
Why this product
Six cores, twelve threads for multitasking
With 6 cores and 12 processing threads, it handles gaming, streaming, and video editing simultaneously without bottlenecking on thread count.
Up to 4.7 GHz Max Boost Clock
A 4.2 GHz base clock rises to 4.7 GHz under load, giving single-threaded workloads the headroom they need for responsive performance.
Overclocking-ready with AMD EXPO™ support
This processor is overclocking-capable, and it supports AMD EXPO™ memory profiles so compatible DDR5 kits can be tuned for higher gaming performance.
Wraith Stealth cooler included
A Wraith Stealth cooler is in the box, so builders can get up and running without purchasing a separate thermal solution.
22MB total cache for fast data access
6MB of L2 cache and 16MB of L3 cache reduce the time the CPU spends waiting on memory, smoothing out load times in games and applications.
PCIe 4 and DDR5-5200 platform support
It supports PCIe Gen 4 graphics cards and storage, plus DDR5 memory up to 5200 MHz and up to 256GB capacity with a compatible motherboard.

- Designed for AM5 socket motherboards — physically and electrically compatible with AM5 only.
- Supported chipsets include A620, B650, B650E, X670, X670E, B840, B850, X870, and X870E.
- Requires DDR5 memory; DDR5-5200 is the rated maximum speed, with EXPO profiles supported for overclocking.
- PCIe Gen 4 is supported; boards with PCIe Gen 5 slots will work, but this processor does not provide Gen 5 CPU lanes.
- Not compatible with AM4 motherboards — the AM5 socket is physically distinct and cannot be adapted.
- No integrated graphics — a discrete GPU is required to produce display output.
Best for
- Builders assembling a new AM5 gaming PC who want a mid-range CPU with a cooler included and overclocking headroom.
- Content creators doing video editing or streaming alongside gaming, where 12 threads distribute work effectively.
- Power-conscious builders who need to stay within a 65W TDP envelope, or who can reduce it further using the 45W cTDP setting.
- Enthusiasts who want tuning control — AMD Ryzen Master, Precision Boost Overdrive, and Curve Optimizer Voltage Offsets are all supported.
Trade-offs
- Buyers with AM4 boards — this processor uses the AM5 socket and cannot be installed in any AM4 platform.
- Builds that need integrated graphics — this processor has no iGPU, so a discrete graphics card is mandatory.
- Workloads that benefit from higher core counts — at 6 cores, heavily threaded professional tasks would be better served by higher-core-count options in the Ryzen lineup.
- DDR4 platform users — DDR5 is required; existing DDR4 memory kits cannot be reused.
With its 6 cores and 12 processing threads, this processor is optimized for high-performance gaming, video editing, and other demanding workloads. Whether you're playing the latest AAA titles or streaming your gameplay, the Ryzen™ 5 8400F processor has the power to keep up. Push your limits and achieve speeds up to 4.7 GHz Max Boost, plus it's unlocked for overclocking.
With a base clock speed of 4.2 GHz and a max boost clock speed of 4.7 GHz in addition to 16MB of L3 Cache, the Ryzen 5 8400F is built to deliver the power needed to smoothly load and multitask demanding applications. You can boost performance further by overclocking this unlocked processor. Other features include support for PCIe Gen 4 technology to take advantage of high-bandwidth graphics cards and storage drives. The Ryzen 5 8400F also supports up to 256GB of 5200 MHz DDR5 memory with compatible motherboards, which may be overclocked using AMD EXPO profiles for higher gaming performance. This processor has a 65W TDP (Thermal Design Power) and includes a Wraith Stealth cooler.
With six cores and 12 threads, the AMD Ryzen 5 8400F 4.2 GHz Six-Core AM5 Processor brings your gaming and content-creation experiences to new levels. Designed for socket AM5 motherboards using the powerful Zen 4 architecture with the 4nm process, this Ryzen processor delivers significantly improved performance compared to its predecessor while maintaining high energy efficiency.
Monitor your system in real-time using the AMD Ryzen Master Utility, which features a histogram of per-core clock rates and temperature, including average and peak readings.
