Cisco Intel Xeon E7-4807 processor 1.86 GHz 18 MB L3

The Intel Xeon Processor E7-8800/4800/2800 Product Families is the second-generation chip multiprocessor (CMP) offering Intel QuickPath Interconnect (Intel QPI) technology in the Intel
Xeon MP processor family of processors. The Intel Xeon Processor E7-8800/4800/2800 Product Families implement up to ten multi-threaded (two thread) cores based upon the Intel Xeon Processor E7-8800/4800/2800 Product Families core design. A large, up to 30 MB, last-level cache (level 3), has been implemented to be shared across all active cores. The Intel Xeon Processor E7-8800/4800/2800 Product Families implement Intel QuickPath Interconnect technology to
replace the traditionally-implemented front-side bus. The Intel Xeon Processor E7-8800/4800/2800 Product Families provides four full width Intel QuickPath Interconnect links, sufficient to implement a glue-less (direct connect) four-processor socket and two IOH solutions, as well as scalable solutions based on OEM-developed external node controllers (referred to as XNC). The Intel Xeon Processor E7-8800/4800/2800 Product Families also integrate two memory controllers
supporting DDR3 memory technology to further enhance memory latency at higher memory capacity. The Intel Xeon Processor E7-8800/4800/2800 Product Families will be implemented on Intel 32-nm process technology and will be binary-compatible with applications running on previous
members of Intel's IA-32/IA-64 microprocessors.
