Template:mpu Xeon E3-1280 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 3.7 GHz with turbo boost of 4 GHz. The E3-1280 V5 has a TDP of 80 Watts and supports up to 64 GB of dual-channel DDR3/4. This MPU has no integrated graphics processor.

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.
