Intel® E7520 and E7320 Chipsets Product BriefThe Intel® E7520 and the Intel® E7320 Chipsets, the next generation Intel dual-processor server chipset technology, enable reduced power consumption, improved platform reliability, and system manageability compared to previous generation server platforms. These chipsets enable new dual-processor servers to deliver outstanding performance, dependability, and value to enterprise front-end, small-medium business (SMB) or high performance computing (HPC) applications.The Intel® E7520 and the Intel® E7320 chipsets include revolutionary PCI Express*1 serial I/O technology and DDR2, the next generation memory technology to help increase I/O bandwidth and reduce system latency for data-intensive applications. The Intel® Xeon® Processor with 800 MHz system bus allows these chipsets to support the Intel® Xeon® processor with Intel® Extended Memory 64 Technology (Intel® EM64T), Hyper-Threading Technology, Enhanced Intel SpeedStep® Technology, and Streaming SIMD Extensions 3 (SSE3) Instructions.The Intel E7520 and E7320 chipsets support a variety of configuration options, allowing platforms to address a wide range of price points and unique application environments. The Intel E7520 memory controller hub (MCH) is designed specifically for performance and volume applications. The Intel E7320 MCH is designed for value dual-processor (DP) platforms.Intel E7520- and Intel E7320-based platforms can be designed to support any of three memory technologies: DDR 266, DDR 333, or DDR2-400. DDR2-400 memory technology is ideal for HPC and memory-intensive applications, providing up to 20% increase in memory bandwidth over DDR 333 and up to a 40% decrease in power consumption.The PCI Express interfaces directly attach Intel and third-party components to the MCH at speeds up to 4 GB/second on each x8 interface. Another option is the Intel® 6700PXH 64-bit PCI hub. It provides two bus segments that support hot plug and can be independently configured up to two PCI-x64/133 MHz segments.Read the full Intel® E7520 and Intel® E7320 Chipsets Product Brief.
