Product Overview
The Intel® E7520 chipset, utilizing next-generation
dual-processor high-bandwidth chipset
technology, enables reduced power consumption
with improved platform reliability and system
manageability compared to previous-generation
solutions. It enables new dual-processor
platforms to deliver outstanding performance,
dependability and value to embedded customers
and their applications.
The Intel E7520 chipset includes revolutionary
PCI Express*1 serial I/O technology and nextgeneration DDR2 memory technology to help
increase I/O bandwidth and reduce system latency
for data-intensive applications. The 800 MHz
system bus allows it to support the Intel® Xeon™

Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation)
without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. See http://www.intel.com/info/em64t for more information including details on which
processors support Intel EM64T or consult with your system vendor for more information.
§
Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor supporting Hyper-Threading Technology and an HT Technology enabled chipset, BIOS and operating
system. Performance will vary depending on the specific hardware and software you use. See http://www.intel.com/info/hyperthreading/ for more information including details on which processors
support HT Technology.
