Abstract

The invention relates to a method for evaluating and predicting GPU performance in a design stage. The method comprises the steps of operating a group of test applications in a to-be-evaluated GPU chip; capturing a group of scalar performance counter and vector performance counter; on the basis of the captured scalar performance counter and vector performance counter, establishing a model for evaluating and predicting the GPU performance for different chip configurations; and predicting a performance score of the GPU chip and identifying a bottleneck in a GPU production line. The invention also relates to a computer system for evaluating and predicting the GPU performance in the design stage.

Description

technical field [0001] The present invention generally relates to computer processing units. Specifically, the present invention relates to a method for evaluating and predicting the performance of a parallel processing unit, in particular to a method for evaluating and predicting the performance of a graphics processing unit (GPU) and a corresponding computer system. Background technique [0002] GPU performance evaluation and prediction is critical for chip architecture design. Chip architects, system-on-chip (SOC) teams, marketing teams, driver teams, and game developers all need to quickly and accurately identify bottlenecks in GPU chips and target them for different chip configurations and different real-world applications such as gaming table signs, typical games, and workstations Traces predict chip performance. Different stakeholders have specific requirements for GPU chips. For example, GPU architecture teams must identify GPU bottlenecks and evaluate performance...
