Xeon E3-1275 v5 is an entry-level server and workstation 64-bit quad-core x86 microprocessor introduced by Intel in October 2015. This Skylake-based chip operates at 3.6 GHz with turbo boost of 4 GHz. The E3-1275 V5 has a TDP of 80 Watts and supports up to 64 GiB of dual-channel DDR4-2133 memory. This MPU has the HD Graphics P530 IGP.

Cache

Main article: Skylake § 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.
