Intel740™ Graphics Accelerator Thermal Design Considerations
20 Application Note 653
5.2 Power Simulation Software
The power simulation software for the Intel740 graphics accelerator is a utility designed to stress
the thermal design power for an Intel740 graphics accelerator when used in conjunction with a
Pentium II processor. The combination of the Pentium II processor along with the high bandwidth
capability of the new enables new levels of graphics performance which are not utilized in most
current software applications. However, it is conceivable that new applications and drivers will be
written which take advantage of this increased bandwidth. To ensure the thermal performance of
the Intel740 graphics accelerator while running future applications, Intel has developed a software
utility which emulates this anticipated power dissipation.
The power simulation software has been developed only for testing Thermal Design Power. Real
future applications may exceed the Thermal Design Power limit for transient time periods. For
power supply current requirements under these transient conditions, please refer to the Intel740
Graphics Accelerator Datasheet for I
CC-740,
the Power Supply Current (Max) specification.
Note: Please contact your local Intel representative for more information about the Intel740™
Graphics Accelerator Power Simulation Software.
