Template:mpu Celeron 3855U is a 64-bit dual-core budget x86 mobile microprocessor introduced by Intel in late 2015. Fabricated on a 14 nm process based on the Skylake microarchitecture, this processor operates at 1.6 GHz. The 3855U has a TDP of 15 W with a configurable-down TDP of 10 W. This chip incorporates the HD Graphics 510 GPU operating at 300 MHz with a burst frequency of 900 MHz. This processor supports up to 32 GiB of non-ECC dual-channel DDR4-2133 memory.

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.
