AMD Ryzen 5 8400F Zen 4 Desktop Processor, 6 Cores/12 Threads, 4.2–4.7GHz, 22MB Cache, AM5, DDR5, PCIe 4.0, 65W, Discrete GPU Required

EXPERT FEATURES Exact Tray SKU — 100-000001591 : This is the AMD Ryzen 5 8400F AM5 tray processor, not its separately identified boxed or MPK versions. Cooler and retail packaging are not confirmed for this tray SKU. 6 Zen 4 Cores / 12 Threads : Simultaneous multithreading gives six physical cores twelve processing threads for gaming with a discrete GPU, multitasking, and everyday desktop work. 4.2GHz Base / Up to 4.7GHz Boost : A 4.2GHz base clock and up to 4.7GHz maximum boost offer responsive processing; achieved boost varies by workload, cooling, and system configuration. 22MB Combined L2 + L3 Cache : The processor provides 6MB of L2 cache and 16MB of L3 cache. These are distinct cache levels, not 22MB of L3. AM5 Motherboard Compatibility : Requires a compatible Socket AM5 motherboard. AMD lists A620, B650/B650E, X670/X670E, B840/B850, and X870/X870E chipsets; check the exact board’s CPU support list and BIOS revision. DDR5 Dual-Channel Memory : Supports DDR5 UDIMM memory across two channels, up to 256GB as AMD specifies. Official maximum speeds are DDR5-5200 with two modules and DDR5-3600 in four-module configurations listed by AMD. PCIe 4.0 Expansion : Provides PCI Express 4.0 with 20 native lanes in total and 16 usable lanes, according to AMD; actual slot wiring and device support depend on the motherboard. Discrete Graphics Card Required : There is no usable integrated graphics processor. Install a compatible dedicated graphics card to obtain normal display output; motherboard video ports alone will not make this CPU display an image. 65W Default TDP : AMD specifies a 65W default TDP and a configurable 45–65W range. TDP is a thermal design rating, not a fixed wall-power or maximum CPU draw figure. Tuning Features : AMD lists an unlocked processor, EXPO memory overclocking, Precision Boost Overdrive, Curve Optimizer, and Ryzen Master; availability and stability depend on the motherboard, BIOS, cooling, and components. NVMe Storage Support : AMD documents NVMe boot support and RAID 0 / RAID 1 capability. Confirm the motherboard’s M.2 slots, lane sharing, and firmware support for your specific SSD configuration. Tray Build Planning : Pair this CPU with compatible AM5 cooling, DDR5 memory, an updated supported motherboard BIOS, and a discrete GPU. The manufacturer does not confirm an included cooler for this tray SKU.
