Intel Celeron CPU 3855U
The Intel Celeron CPU 3855U is a 2015 dual-core processor for entry-level laptops, based on the Skylake microarchitecture.
The Intel Celeron CPU 3855U is a dual-core, dual-thread processor released in December 2015 as part of the Skylake microarchitecture. It has a base clock of 1.60 GHz with 2 MB L3 cache and 0.5 MB L2 cache. The processor is built on a 14 nm process with a TDP of 15 W, making it suitable for thin and light laptops. It supports DDR4-1866/2133, LPDDR3-1600/1866, and DDR3L-1333/1600 memory across two channels, but does not support ECC memory. Integrated graphics are provided by Intel HD Graphics 510. The CPU offers 10 PCIe 2.0 lanes and supports 64-bit computing along with Intel SSE4.1 and SSE4.2 instruction sets. The multiplier is locked, and the processor uses the FCBGA1356 socket. It was discontinued on September 30, 2022, with a launch MSRP of $107.
