摘要：Technologies are presented that optimize graphics processing performance. A method of frequency scaling may include beginning a graphics workload with a starting geometry preprocessing frequency of a multiple of a streaming shader engine frequency where the multiple is non-zero; determining a primitive start pitch for a primitive of the graphics workload; comparing the determined primitive start pitch to a predetermined threshold and, if it exceeds the predetermined threshold: reducing the geometry preprocessing frequency, and, at the start of the next primitive, setting the geometry preprocessing frequency back to the starting geometry preprocessing frequency; and repeating the determining and comparing for each remaining primitive until an end of the graphics workload. Performance gain based on primitive start pitch information may also be determined.

主权项：1. A method, comprising: pre-processing data in a graphics processor at a first clock frequency; post-processing the data across multiple slices of the graphics processor, subsequent to the pre-processing, at a second clock frequency; and controlling a difference between the first and second clock frequencies based on a workload of the post-processing.
