Intel Xeon 5200 Dual Core Processors
The Dual-Core Intel Xeon 5200 Series processors utilizes two 45 nm Hi-k next generation Intel Core
microarchitecture cores. The processors feature fast data throughput with Intel I/O Acceleration
Technology, up to 6 MB of L2 cache memory that can be allocated entirely to one core, and they
support both 32-bit and 64-bit applications. The energy-efficient processors are optimized for low-
power, dual-core, 64-bit computing.
Intel Core Mircroarchitecture integrates an efficient 14-stage pipeline and memory architecture design
for greater processor throughput with power management technologies that reduce power
consumption without affecting performance. The architecture also supports direct L1-to-L1 cache
transfer and improved memory pre-fetch.
Other technologies featured in the Intel Xeon 5200 processors include:
• Hyper-Threading Technology — described in “Hyper-Threading Technology” on page 11.
• Intel Virtualization Technology — provides hardware assistance for software-based virtual
environments to support new capabilities, including 64-bit operating systems and applications.
• Intel I/O Acceleration Technology (I/OAT) — hardware and software supported I/O acceleration that
improves data throughput. Unlike NIC-centric solutions (such as TCP Offload Engine), I/OAT is a
platform level solution that addresses packet and payload processing bottlenecks by implementing
parallel processing of header and payload. It increases CPU efficiency and delivers data to and from
applications faster with improved direct memory access (DMA) technologies that reduce CPU
utilization and memory latencies associated with data movement. Finally, I/OAT optimizes the TCP/IP
protocol stack to take advantage of the features of the high bandwidth rates of modern Intel
processors, thus diminishing the computation load on the processor.
