Technology Overview

The Nehalem-EP Platform is Intel's next generation technology that takes server computing to unprecedented heights. Offering up to 2.25x more performance than the last generation Xeon CPUs and over 3x the bandwidth, this new platform has power to spare. With new advanced options such as native support for SSD and 10 GbE, your server systems stay atop of the technology curve. Intelligent hardware design has created the most efficient server CPU, lowering energy and IT costs. A flexible design architecture allows the same server to fulfill multiple roles saving design costs and an overcall lower TCO than previous designs.

Server Performance Benchmarks

Performance is improved drastically compared to last generation platforms with faster clock speeds, enhanced bandwidth, and a more efficient CPU architecture.

Data source: Intel Internal measurements – Nov 2008; For Server SPECjbb2005, SPECint_rate on HTN 3.33; Others on HTN 3.16 Performance tests and ratings are measured using specific computer systems and/or components and reflect the approximate performance of Intel products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should consult other sources of information to evaluate the performance of systems or components they are considering purchasing.

The Intel® Xeon® processor 5500 series includes an integrated memory controller supporting high-speed, three-channel DDR3 memory. DDR3 enables higher capacity, higher performance, and lower power than DDR2-based systems. This platform supports multiple DDR3 DIMM types:

  • Registered DIMMs (RDIMM)
  • ECC unbuffered DIMMs (UDIMM ECC)
  • Unbuffered DIMMs (UDIMM)
  • MetaRAM DIMMs

With more differentiation between the processor lines, choose the CPU and memory based upon your workload and environment. Buying a higher ROI leads to decreased TCO by 20% and increasing performance by 30%.

Intel 5500 Series Tylersburg Chipsets

The 5500 Series chipset (codename "Tylersburg") is the new point of contact for the Xeon 5500 series processors. Utilizing the new QuickPath Connect technology with a maximum bandwidth of 51.2 GB/s (25.6 GB/s per CPU), the hub can supply more than enough data bandwidth for powerful video cards, extremely fast SSD and SAS hard drives, and new 10 GbE adapters.

Benefits of the new architecture:

  • Decreased memory latency (on-die memory controller)
  • Support for HyperThreading
  • Faster and more efficient power states
  • Intel® VT for Directed I/O: (chipset) - speeds data movement through direct VM (Virtual Machine) to device assignment
