Ever-increasing graphics performance boosts demands on power subsystem

CHiL Semiconductor Corporation, a leading developer of high-performance, mixed-signal power management integrated circuits for the server, personal computer and high-volume computing market segments, discusses how CHiL products increase GPU performance in a recently posted podcast at The discussion focuses on increasing performance by using precise digital control of the power subsystem.

Charles Bailley, a senior engineer at CHiL, provides background on how increased performance and functionality puts exponentially increased demand on the power delivery subsystem. He explains why graphics processors need precise digital control of their power subsystems to improve GPU performance, and provides specifics on how the CHiL VR controller increases GPU performance.

“To continue increasing the computing density of the graphics platform, the power density of the graphics platform must also increase, which in turn requires higher efficiency from its power delivery sub-system,” says Bailley. “CHiL’s new VR controllers provide the highest efficiency, lowest cost of ownership solution in the industry.”

The CHiL VR controller provides telemetry to determine when the graphics platform is at peak performance, but also provides a safety net against breaching a system power limit. The power delivery sub-system can be configured to control input supply current from each of multiple input power sources, to maximize the total overall power delivered to the graphics platform. Also, the controller allows the power delivery sub-system to reduce power consumption during idle compute cycles, improving the system’s overall efficiency of the system.
