Intel Pentium CPU 6405U
The Intel Pentium CPU 6405U is a 2019 dual-core processor for laptops, based on the Comet Lake microarchitecture.
The Intel Pentium CPU 6405U is a dual-core processor with four threads, released in October 2019. It has a base clock of 2.40 GHz and a 2 MB L3 cache, built on a 14 nm process. The CPU has a TDP of 15 W, making it suitable for thin and light laptops. It supports DDR4-2400 and LPDDR3-2133 memory across two channels, but does not support ECC memory. Integrated graphics are Intel UHD Graphics for 10th Gen Intel Processors. The processor uses the FCBGA1528 socket and provides 12 PCIe 2.0 lanes. It supports 64-bit computing and Intel SSE4.1/4.2 instruction sets. The multiplier is locked. The CPU was discontinued in January 2020.
