Introduction

The Intel

Xeon

Processor 5500 Series is the first-generation server/workstation

multi-core processor to implement key new technologies:

• Integrated Memory Controller
• Point-to-point link interface based on Intel

QuickPath Technology

The processor is optimized for performance with the power efficiencies of a low-power
microarchitecture to enable smaller, quieter systems.

This document provides DC electrical specifications, differential signaling specifications,
pinout and signal definitions, package mechanical specifications and thermal
requirements, and additional features pertinent to implementation and operation of the
processor. For information on register descriptions, refer to the Intel

5500 Series Datasheet, Volume 2

Intel Xeon Processor 5500 Series are multi-core processors, based on 45 nm process
technology. The processor family features a range of thermal design power (TDP)
envelopes from 38W TDP up to 130W TDP. These processors feature two Intel
QuickPath Interconnect point-to-point links capable of up to 6.4 GT/s, up to 8 MB of
shared cache, and an Integrated Memory Controller. The processors support all the
existing Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3)
and Streaming SIMD Extensions 4 (SSE4). The processors support several Advanced
Technologies: Execute Disable Bit, Intel

64 Technology, Enhanced Intel SpeedStep

Technology, Intel

Virtualization Technology (Intel

VT), Intel

Hyper-Threading

Technology (Intel

HT Technology), and Intel

Turbo Boost Technology (Intel

TBT).

The Intel Xeon Processor 5500 Series family supports multiple platform segments.

• 2-Socket Workstation Platforms support Intel

Xeon

Processor W5580, a 130W

Thermal Design Power (TDP) SKU. These platforms provide optimal overall
performance and reliability, in addition to high-end graphics support. Note, specific
platform usage conditions apply when implementing these processors.

• 2-Socket High Performance Server and High Performance Computing (HPC)

Platforms support Intel Xeon Processor 5500 Series Advanced SKU (95W TDP).
These platforms provide optimal overall performance.

• 2-Socket Volume Server Platforms support Intel Xeon Processor 5500 Series

Standard/Basic SKUs (80W TDP). These platforms provide optimal performance per
watt for rack-optimized platforms.

• Ultra Dense Platforms implement Intel Xeon Processor 5500 Series Low Power SKU

(60W TDP). These processors are intended for dual-processor server blades and
embedded servers.

• Intel

Xeon

Processor L5518 with 60W TDP and elevated case temperatures. The

elevated case temperatures are intended to meet the short-term thermal profile
requirements of NEBS Level 3. These 2-Socket processors are ideal for thermally-
constrained form factors in embedded servers, comms and storage markets.

• Intel

Xeon

Processor L5508 with 38W TDP and elevated case temperatures. The
