The Intel Core i5-11400T was a desktop processor with 6 cores, launched in March 2021, at an MSRP of $182. 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 i5-11400T has 12 MB of L3 cache and operates at 1300 MHz by default, but can boost up to 3.7 GHz, depending on the workload. Intel is building the Core i5-11400T on a 14 nm production process, the transistor count is unknown. The multiplier is locked on Core i5-11400T, which limits its overclocking capabilities.
With a TDP of 35 W, the Core i5-11400T consumes only little energy. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 3200 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Core i5-11400T uses a PCI-Express Gen 4 connection. This processor features the UHD Graphics 730 integrated graphics solution.
Hardware virtualization is available on the Core i5-11400T, 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 has added support for the newer AVX2 and AVX-512 instructions, too.
