AMD Athlon™ 64 and AMD Opteron™ Processors
Thermal Design Guide
Chapter 1 Introduction
This document specifies performance requirements for the design of thermal and mechanical
solutions for the AMD Athlon™ 64 and AMD Opteron™ processors, utilizing AMD64
architecture. Detailed drawings, descriptions, and design targets are provided to help
manufacturers, suppliers, and engineers meet requirements for the AMD Athlon 64 and
AMD Opteron processors.
1.1 Summary of Requirements
To allow optimal reliability of the AMD Opteron and AMD Athlon 64 processor-based systems,
the thermal and cooling solution should dissipate heat from a processor operating at its maximum
thermal power. The sections in this document specify required values for the thermal and
mechanical parameters. This document provides two methods of creating a solution that satisfy the
thermal and mechanical requirements for these processors. By setting a high-power target for the
initial design, the thermal-design engineer may avoid redesign of the processor cooling solution
for subsequent processors.
