Power subsystem-monitoring-based graphics processing system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a throttling engine that is configured to:
• monitor a power draw via a power subsystem coupled to the processing system;
• activate a first throttling of a Graphics Processing Unit (GPU) that is coupled to the processing system when the power draw via the power subsystem that powers the GPU exceeds a power subsystem maximum power consumption that is obtained by performing a database lookup, and deactivate the first throttling of the GPU when the power draw via the power subsystem no longer exceeds the power subsystem maximum power consumption;
• activate a second throttling of the GPU when the power draw via the power subsystem exceeds a power subsystem rated power consumption for a first time period, and deactivate the second throttling of the GPU when the power draw via the power subsystem no longer exceeds the power subsystem rated power consumption;
• and
• reduce the operating capabilities of the GPU when the second throttling has been performed for more than a second time period, and increase the operating capabilities of the GPU when the second throttling has been performed for less than the second time period and the GPU is operating below a GPU predetermined operating capability.

A method for providing power-subsystem-monitoring-based computing, comprising:

• monitoring, by a throttling subsystem, a power draw of a power subsystem;
• activating, by the throttling subsystem, a first throttling of a first computing component when the power draw via the power subsystem that powers the first computing component exceeds a power subsystem maximum power consumption that is determined using an identifier for the power subsystem, and deactivating the first throttling of the first computing component when the power draw via the power subsystem no longer exceeds the power subsystem maximum power consumption;
• activating, by the throttling subsystem, a second throttling of the first computing component when the power draw via the power subsystem exceeds a power subsystem rated power consumption for a first time period, and deactivating the second throttling of the first computing component when the power draw via the power subsystem no longer exceeds the power subsystem rated power consumption;
• and
• reducing, by the throttling subsystem, the operating capabilities of the first computing component when the second throttling has been performed for more than a second time period, and increasing the operating capabilities of the first computing component when the second throttling has been performed for less than the second time period and the first computing component is operating below a first computing component predetermined operating capability.
