Atom C3850 is a 64-bit dodeca-core ultra-low power x86 microserver system on a chip introduced by Intel in 2017. The C3850, which is manufactured on a 14 nm process, is based on the Goldmont microarchitecture. This chip operates at 2.1 GHz with a TDP of 25 W and a turbo boost frequency of up to 2.4 GHz. The C3850 supports up to 256 GiB of dual-channel DDR4-2133 ECC memory. This model is part of Denverton's Server and Cloud Storage SKUs.

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.
