Dual-Core Intel® Xeon® Processor
Delivering Eight-Thread Capability to DP Servers

Introducing Intel’s first dual-core processor for DP platforms.
Intel’s first dual-core server processor unleashes a new era of server performance and flexibility, providing businesses with platforms that can better handle complex, simultaneous transactions and escalating workloads.

Dual-Core Intel® Xeon® processor-based server platforms are the ideal solution for multithreaded and multi-task usage environments. Based on the widely deployed Intel® E7520 chipset, these processors deliver performance gains of up to 51%1, and are backwards-compatible with all 64-bit Intel® Xeon® processors.

Multi-Core architecture: Intel’s roadmap for the future.
Intel recognizes that the need for platforms with the right type of compute power and performance will continue to escalate over time. The evolution is likely to include better recognition applications and search functions that enable seamless mining of information, and support knowledgeable, data-based decision making.

As these and other emerging consumer- and business-usage models become mainstream, they will require increasingly more compute power. A comprehensive threading strategy that advances the platform—through Hyper-Threading Technology2 (HT Technology), dual-core processors, and eventually multi-core processors—is crucial to delivering this compute power.

Intel has been driving toward parallelism for more than a decade: first with multiprocessor platforms, then with HT Technology, and now with dual-core processing. Going forward, Intel will continue to focus its efforts on technologies that help make the balanced platform a reality.

With 64-bit Intel Xeon processor-based server platforms, you know you’re getting a proven platform with the flexibility to take you into the future.
There are compelling reasons to move your business to 64-bit computing now. 64-bit computing with Intel Xeon processors gives you additional application headroom, I/O headroom, improved reliability, lower power consumption, memory flexibility, and increased security.

By supporting larger data sets and both 32- and 64-bit applications, 64-bit Intel Xeon processor-based servers allow the smooth migration of your business solutions to 64-bit applications. And with over six million 64-bit processors already shipped, you know you can depend on Intel’s proven track record to help you make a smooth transition to the next generation of computing.

The performance, reliability, and flexibility customers demand.
Dual-Core Intel Xeon processors deliver enhanced platform performance and dependability through a variety of innovative technologies that include the following:

• New dual-core processors improve processor throughput by increasing CPU resources.
• Increased performance, with up to 51%1 increase compared to prior-generation, single-core platforms.
• Get faster response times with double the L2 cache as compared to the previous generation of Intel Xeon processors.
• Intel® Extended Memory 64 Technology3 (Intel® EM64T) provides application flexibility with support for 64-bit computing.
• HT Technology supports the execution of more than one instruction set at a time, resulting in a new level of system performance and responsiveness when multi-tasking.
• Enhanced HALT state (C1E) reduces the processor speed and voltage when in idle mode to decrease power consumption and heat generation.
• Take advantage of power savings and increased system density for server applications by using Demand-Based Switching (DBS) with Enhanced Intel SpeedStep® technology. New functionality has been added to the Dual-Core Intel Xeon processor 2.80 GHz to enable support for DBS.
• Scalable bandwidth with PCI Express*, an I/O technology that matches the performance and capabilities of next-generation serial interconnects.
• DDR2-400 memory-based subsystem offers lower latency while consuming less power.
• Help prevent certain classes of malicious “buffer overflow” and worm attacks with Intel’s Execute Disable Bit functionality.

Target applications
Servers based on 64-bit Intel Xeon processors are the most widely deployed in the world, because they can do virtually anything business demands of them, worry-free. And Dual-Core Intel Xeon processors take that performance even further, offering compelling value for database, Web, and mail applications.
