Xeon E7-2803 is a 64-bit hexa-core x86 data center microprocessor that supports up to 2 sockets. This first generation (Westmere-based) Xeon E7 processor operates at 1.73 GHz with a TDP of 105 W but does not support turbo boost technology. This processor supports up to 4 channels of DDR3, supporting up to 1 TB of memory.

Cache

Main article: Westmere § 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.
