Nvidia Driver Unlocks Performance Boosting GPU System Processor

As shared in a recent Nvidia document for Linux, Nvidia has quietly unlocked a new feature in its enterprise and consumer GPUs that's been in hiding since the Turing generation. Known as the GSP or GPU System Processor, this piece of silicon offloads driver duties from the CPU onto the GPU to improve performance and efficiency. It was officially unlocked for use in the latest Nvidia drivers.

The feature is available now if you have a qualifying enterprise Nvidia GPU and Nvidia driver 510.39.01 or later. GPU support ranges from the Turing-based Tesla T4, all the way to the Nvidia A series, such as the A100, A2, and A40.

In a new YouTube video released today, Nvidia explains how its latest version of Max-Q will maximize efficiency between the CPU and GPU. One of those features includes GSP -- but in this instance, Nvidia calls it a "command processor" instead of a GPU System Processor.

We believe the GSP and "command processor" are the same thing since they function in the same way by offloading low-level tasks from the CPU to the GPU in an effort to improve performance. In the case of Max-Q, Nvidia gives the example of command validation, which performs pointer verification and balance checking, and how this workload will be transitioned from the CPU to the GPU for better performance.

We still don't know a lot about GSP, like its actual performance benefits or its full functionality. However, we expect we'll know more soon as Nvidia continues to develop this feature in 2022.
