Intel Core i5-10400F Processor

The Intel Core i5-10400F is a 10th Generation Comet Lake desktop processor designed for mainstream builders who want a real 6-core, 12-thread CPU without paying for integrated graphics. Built on Intel’s 14 nm process, it pairs a 2.9 GHz base clock with a 4.3 GHz max turbo (Intel Turbo Boost 2.0) and 12 MB of Intel Smart Cache, giving it the headroom needed for 1080p gaming, day-to-day productivity, light content creation and everyday multitasking. Because the “F” suffix denotes a disabled iGPU, the i5-10400F is intended for systems with a discrete graphics card – making it a popular pairing with budget GeForce and Radeon GPUs in value-focused gaming builds. Hyper-Threading is enabled, so all 6 physical cores expose 12 logical threads to the OS, which helps in modern games and lightly threaded creator workloads such as photo editing, streaming and code compilation. The processor uses the FCLGA1200 socket and is compatible with Intel 400-series and select 500-series chipsets (H410, B460, H470, Z490, B560, H510, Z590 – confirm BIOS support with your motherboard vendor). It officially supports up to 128 GB of DDR4-2666 memory across two channels, delivering up to 41.6 GB/s of memory bandwidth, and exposes 16 PCIe 3.0 lanes for the graphics card plus chipset-side lanes for NVMe storage. Intel Optane Memory is supported on compatible platforms. With a 65 W TDP and PCG 2015C thermal specification, the i5-10400F runs comfortably on the bundled Intel stock cooler in typical chassis, while still leaving room for a quieter aftermarket air cooler if preferred. Intel platform features include AES-NI, SGX (with Intel ME), OS Guard, Boot Guard, VT-x and VT-d virtualization and Enhanced SpeedStep. Key verified specifications: 10th Gen Intel Core i5 (Comet Lake), 6 cores / 12 threads, 2.9 GHz base / 4.3 GHz max turbo, 12 MB Intel Smart Cache, LGA1200 (FCLGA1200) socket, DDR4-2666 dual-channel up to 128 GB, PCIe 3.0 (up to 16 lanes), 14 nm lithography, 65 W TDP, no integrated graphics, Intel stock cooler included, 3-year manufacturer warranty (SKU BX8070110400F, GTIN 5032037187114). Best suited to: budget and mid-range 1080p gaming builds, office and home productivity PCs, and LGA1200 upgrades where a discrete GPU is already planned. Less ideal for: builds that need integrated graphics, heavy multi-threaded rendering or workstation workloads where higher core-count Core i7/i9 or newer-generation chips will scale better
