The Intel Core i5-14401E is a desktop processor with 6 cores, launched in July 2024. It is part of the Core i5 lineup, using the Raptor Lake Refresh architecture with Socket 1700. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 12 threads. Core i5-14401E has 20 MB of L3 cache and operates at 2.5 GHz by default, but can boost up to 4.7 GHz, depending on the workload. Intel is making the Core i5-14401E on a 10 nm production node, the transistor count is unknown. The multiplier is locked on Core i5-14401E, which limits its overclocking potential.
With a TDP of 65 W, the Core i5-14401E consumes typical power levels for a modern PC. Intel’s processor supports DDR4 and DDR5 memory with a dual-channel interface. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the computer, Core i5-14401E uses a PCI-Express Gen 5 connection. This processor features the UHD Graphics 730 integrated graphics solution.
Hardware virtualization is available on the Core i5-14401E, 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.
