Xeon E3-1280 v6 is a 64-bit quad-core x86 workstation/entry server microprocessor introduced by Intel in early 2017. This chip, which is based on the Kaby Lake microarchitecture, is fabricated on Intel's 14nm+ process. The E3-1280 v6 operates at 3.9 GHz with a TDP of 72 W supporting a Turbo Boost frequency of 4.2 GHz. The processor supports up to 64 GiB of dual-channel DDR4-2400 ECC memory. This model has no integrated graphics processor.

Cache

Main article: Kaby Lake § 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.
