The Intel Core i5-11400 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 i5-11400 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 making the Core i5-11400 on a 14 nm production node, the transistor count is unknown. The multiplier is locked on Core i5-11400, which limits its overclocking potential.
With a TDP of 65 W, the Core i5-11400 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 computer, Core i5-11400 uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics 730 integrated graphics solution.
Hardware virtualization is available on the Core i5-11400, 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) can 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.
