Xeon E7-2820 is a 64-bit octa-core x86 data center microprocessor that supports up to 2 sockets. This first generation Xeon E7 processor, Westmere-based, operates at a base frequency of 2 GHz with turbo frequency of 2.266 GHz for 2 active cores. This chip has a TDP of 105 W, supporting up to 4 channels of DDR3 with support of up to 1 TB of memory.

Cache[edit]

[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.
