3 Thermal Specifications

3.1Thermal Design Power (TDP)

Analysis indicates that real applications are unlikely to cause the PXH component to consume maximum power dissipation for sustained time periods. Therefore, in order to arrive at a more realistic power level for thermal design purposes, Intel characterizes power consumption based on known platform benchmark applications. The resulting power consumption is referred to as the Thermal Design Power (TDP). TDP is the target power level that the thermal solutions should be designed to. TDP is not the maximum power that the chipset can dissipate.

For TDP specifications, see Table 3-1 for the PXH component. Flip chip ball grid array (FC-BGA) packages have poor heat transfer capability into the board and have minimal thermal capability without a thermal solution. Intel recommends that system designers plan for a heatsink when using the PXH component.

3.2Die Case Temperature Specifications

To ensure proper operation and reliability of the PXH component, the die temperatures must be at or between the maximum/minimum operating temperature ranges as specified in Table 3-1Table 3- 1Table 3-1. System and/or component level thermal solutions are required to maintain these temperature specifications. Refer to Chapter 5 for guidelines on accurately measuring package die temperatures.
