Core i5-11400F

The Core i5-11400F is a 6-core / 12-thread processor based on the Rocket Lake (2021) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.4 GHz from a base frequency of 2.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 12 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 16,902, placing it in the Mid-Range performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,000, while multi-core reaches 7,600.

The Core i5-11400F fits into the LGA1200 socket and supports PCIe 4.0 with 20 total PCIe lanes for expansion cards and storage. It supports DDR4 memory at speeds up to DDR4-3200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 128 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: None — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core i5-11400F is primarily designed for Mainstream Desktop. It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: VT-x, VT-d — enables running virtual machines efficiently (important for development and server workloads).

The Core i5-11400F has a rated TDP (Thermal Design Power) of 65 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. It ships with the Included stock cooler. Recommended cooling: Standard.

At an average price of $110 (MSRP: $157), the Core i5-11400F delivers 154 PassMark points per dollar. Performance ranking position: #932 out of all indexed processors.
