Atom C3708 is a 64-bit octa-core ultra-low power x86 microserver system on a chip introduced by Intel in 2017. The C3708, which is manufactured on a 14 nm process, is based on the Goldmont microarchitecture. This chip operates at 1.7 GHz with a TDP of 17 W. The C3708 supports up to 256 GiB of dual-channel DDR4-2133 ECC memory. This model is part of Denverton's Internet of Things and eTEMP SKUs which come with integrated QuickAssist Technology and support extended ambient operating temperature (-40 °C to 85 °C).

Cache

Main article: Goldmont § Cache

[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.
