The Intel Core i5-12400 is a desktop processor with 6 cores, launched in January 2022. It is part of the Core i5 lineup, using the Alder Lake-S architecture with Socket 1700. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Core i5-12400 has 18MB of L3 cache and operates at 2.5 GHz by default, but can boost up to 4.4 GHz, depending on the workload. Intel is building the Core i5-12400 on a 10 nm production process, the transistor count is unknown. The multiplier is locked on Core i5-12400, which limits its overclocking capabilities.
With a TDP of 65 W, the Core i5-12400 consumes typical power levels for a modern PC. Intel’s processor supports DDR4 and DDR5 memory with adual-channel interface. For communication with other components in the machine, Core i5-12400 uses a PCI-Express Gen 5 connection. This processor features the UHD Graphics 730 integrated graphics solution.
Hardware virtualization is available on the Core i5-12400, 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 is including the newer AVX2 standard, too, but not AVX-512.
