Description
Intel Core i5-12400F Processor - 6-Core, 2.5 GHz arrived in Q1'22 as part of Intel's 12th Gen Alder Lake family, offering strong desktop performance for gaming and mainstream workloads.
The Intel Core i5-12400F is a 6-core, 12-thread processor built for the LGA1700 socket and features a 2.5 GHz base frequency with a performance-core boost up to 4.4 GHz. With 18 MB of Smart Cache and a Thermal Design Power of 65 W (maximum turbo power 117 W), it balances efficiency and burst performance.
This boxed CPU includes a cooler and supports both DDR4 and DDR5 memory types in dual-channel configurations, with up to 128 GB maximum internal memory and a theoretical memory bandwidth of 76.8 GB/s. The chip supports modern platform features such as PCI Express 5.0/4.0 with up to 20 lanes and DMI4 connectivity.
Security and manageability are well covered, with Intel features like AES-NI, Boot Guard, CET, Intel® Secure Key, Intel VT-x/VT-d, Intel OS Guard and Enhanced Halt State. The processor also includes DL Boost and Intel GNA 3.0 for AI and low-power signal processing tasks.
Designed for desktop gaming and PC/client use, the i5-12400F is ideal when paired with a discrete graphics card, as it has no integrated GPU. Its Alder Lake architecture and support for PCIe 5.0 make it future-proof for high-speed storage and next-gen graphics cards.
Typical use cases include mainstream gaming rigs, productivity desktops for content creation and streaming, and budget-conscious workstations that need strong single-threaded and multi-threaded performance without integrated graphics.
Key selling points are the 6 high-performance cores with 12 threads, 4.4 GHz boost, 18 MB Smart Cache, boxed package with cooler, support for DDR4/DDR5 memory, and compatibility with LGA1700 motherboards and PCIe 5.0 devices.
