The Intel Core i5-11400F is a desktop processor with 6 cores, launched in March 2021. It is part of the Core i5 lineup, using the Rocket Lake-S architecture with Socket 1200. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Core i5-11400F has 12MB of L3 cache and operates at 2.6 GHz by default, but can boost up to 4.4 GHz, depending on the workload. Intel is building the Core i5-11400F on a 14 nm production process, the transistor count is unknown. The multiplier is locked on Core i5-11400F, which limits its overclocking capabilities.
With a TDP of 65 W, the Core i5-11400F consumes typical power levels for a modern PC. Intel’s processor supports DDR4 memory with adual-channel interface. The highest officially supported memory speed is 3200 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, Core i5-11400F uses a PCI-Express Gen 4 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Core i5-11400F, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel has added support for the newer AVX2 and AVX-512 instructions, too.
