The Intel Core i5-9400 is a desktop processor with 6 cores, launched in October 2018. It is part of the Core i5 lineup, using the Coffee Lake Refresh architecture with Socket 1151. Core i5-9400 has 9MB of L3 cache and operates at 2.9 GHz by default, but can boost up to 4.1 GHz, depending on the workload. Intel is making the Core i5-9400 on a 14 nm production node, the transistor count is unknown. The multiplier is locked on Core i5-9400, which limits its overclocking potential.
With a TDP of 65 W, the Core i5-9400 consumes typical power levels for a modern PC. Intel's processor supports DDR4 memory with adual-channel interface. For communication with other components in the system, Core i5-9400 uses a PCI-Express Gen 3 connection. This processor features the UHD 630 integrated graphics solution.
Hardware virtualization is available on the Core i5-9400, 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 is including the newer AVX2 standard, too, but not AVX-512.
