For high performance multi-processor designs, where the aim is to provide the maximum possible compute performance in a given volume, we are entering an era where such boards may need to be operated at a de-rated performance level when operated at the industry standard 85 degrees Celsius card-edge, and 71 degrees Celsius inlet temperature conditions. This introduces a new element of power management for system designers to consider.
This paper discusses the behavior of the Intel Core i7 processor, as implemented on the Curtiss-Wright Controls Embedded Computing multi-processor CHAMP-AV series products at elevated temperatures, and how to take advantage of board features to maximize the performance potential of the system.
