The Intel Core i5-10400H is a mobile processor with 4 cores, launched in April 2020. It is part of the Core i5 lineup, using the Comet Lake-H architecture with BGA 1440. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 8 threads. Core i5-10400H has 6 MB of L3 cache and operates at 2.6 GHz by default, but can boost up to 4.6 GHz, depending on the workload. Intel is building the Core i5-10400H on a 14 nm production process, the transistor count is unknown. The multiplier is locked on Core i5-10400H, which limits its overclocking capabilities.
With a TDP of 45 W, the Core i5-10400H consumes typical power levels for a modern PC. Intel's processor supports DDR3 and DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 2933 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, Core i5-10400H uses a PCI-Express Gen 3 connection. This processor features the UHD Graphics integrated graphics solution.
Hardware virtualization is available on the Core i5-10400H, 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.
