Roofman (often stylized as roofman-vpx ) focuses on . This is a performance model used to provide performance estimates of a given compute kernel or application by showing how it relates to hardware limitations like memory bandwidth and peak computational throughput. Key features of the Roofman libvpx integration include: : The successor that offers roughly 50% better
