Xeon E3-1285 v6 is a 64-bit quad-core x86 workstation/entry server microprocessor introduced by Intel in mid-2017. This chip, which is based on the Kaby Lake microarchitecture, is fabricated on Intel's 14nm+ process. The E3-1285 v6 operates at 4.1 GHz with a TDP of 79 W and a Turbo Boost frequency of up to 4.5 GHz. The processor supports up to 64 GiB of dual-channel DDR4-2400 ECC memory and incorporates Intel's HD Graphics P630 IGP operating at 350 MHz with a burst frequency of 1.15 GHz.

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.
