Product Description

Intel Core i5-11400 is an entry-level desktop microprocessor in Intel's 11th-gen Core, Rocket Lake family. Unlike higher-powered SKUs, the i5-11400 and its derivative the i5-11400T only use Intel UHD 730 graphics, which is an additional step down besides the frequency decrease.
Like its predecessor and other i5 models this year, the i5-11400 comes with 6 cores and 12 threads. Intel claims that up to 22% IPC (instructions per clock) increase may be observed over the 10th-gen Comet Lake units under the best-case scenarios.
The new Rocket Lake processors support DDR4-3200MHz memories, though the i5-11400 defaults to 2:1 ratio of DRAM to memory controller at this frequency. Intel also includes PCIe 4.0 support with up to 20 lanes.
Alongside the i5-11400, Intel also markets the Core i5-11400F. The "F" designation means the i5-11400F does not come with the integrated graphics. There is also a low-powered i5-11400T with 35W TDP rather than the 65W TDP of the base model; it also offers a TDP-down mode that is missing from the base i5-11400.
