Intel® Xeon® Processor 7500 Series Datasheet, Vol. 2
The Intel® Xeon® processor 7500 series (formerly code named Nehalem-EX) is the first-generation chip multiprocessor (CMP) offering Intel® QuickPath Interconnect (Intel® QPI) technology in the Intel Xeon processor MP family of processors. The Intel Xeon processor 7500 series implements up to eight multi-threaded (two thread) cores based up...on the Intel Xeon processor 7500 series core design. A large, up to 24-MB, last-level cache (level 3), has been implemented to be shared across all active cores. The Intel Xeon processor 7500 series implements Intel QuickPath Interconnect technology to replace the traditionally-implemented front-side bus. The Intel Xeon processor 7500 series 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 7500 series also integrates two memory controllers supporting DDR3 memory technology to further enhance memory latency at higher memory capacity. The Intel Xeon processor 7500 series will be implemented on Intel 45-nm process technology and will be binary-compatible with applications running on previous members of Intel's IA-32/IA-64 microprocessors.
