Cisco Intel Xeon DP 5600 E5645 Hexa-core (6 Core) 2.40 GHz Processor Upgrade - 12 MB L3 Cache - 1.50 MB L2 Cache - 384 KB L1 Cache - 64-bit Processing - 32 nm - Socket B LGA-1366 - 80 W

The Intel Xeon processor 5600 series automatically regulates power consumption and intelligently adjusts server performance according to application demand, maximizing both energy cost savings and performance. Based on new 32nm Intel microarchitecture, the Intel Xeon processor 5600 series reduces energy cost over single-core servers by automatically shifting the CPU and memory into the lowest available power state, while intelligently adjusting performance to application needs.
