Dynamic graphics geometry preprocessing frequency scaling and prediction of performance gain

Abstract

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.
