Testing the AOMedia libavif encoding of a JPEG image to AV1 Image Format (AVIF). There are five workloads with the first ones taking longer and the later ones quicker.
Overall a moderate retirement rate that is gated by frontend latency more than other areas.
AMD metrics show a moderate floating point and some L2 access but not much beyond L2.
