The Intel Celeron CPU 3865U is a 2017 dual-core processor for entry-level laptops, based on the Kaby Lake microarchitecture. It features two cores and two threads with a base clock of 1.80 GHz, and includes 0.5 MB of L2 cache and 2 MB of L3 cache. Manufactured on a 14 nm process, it has a TDP of 15 W and uses socket BGA 1356. The processor supports DDR4-2133, LPDDR3-1866, and DDR3L-1600 memory across two channels, but does not support ECC memory. It integrates Intel HD Graphics 610 and provides 10 PCIe 2.0 lanes. The CPU supports 64-bit computing and SSE4.1/SSE4.2 instruction sets, but has an unlocked multiplier. It was released in January 2017 with an MSRP of $107 and was discontinued in December 2024.
