The user wants hardware video encoders (like AMD AMF and NVIDIA NVENC) to be able to utilize all the features of video compression standards (like H.265) to achieve the same quality as software encoders (like x265) at a given file size/bitrate.
**As an example**, H265 is a video compression standard and it has several implementations. x265 uses the CPU to do software encoding and it has different encoding preset from Ultrafast to Placebo which affects the video quality at given file size/bitrate. There are hardware video encoders from AMD (AMF) and NVIDIA (NVENC) that can do H265, but they are inferior to x265 in terms of video quality at given file size/bitrate. AMD has made a dedicated accelerator called Alveo, but even their marketing claims their implementation of H265 is equivalent to x265 Medium and x265 slow for their implementation of AV1. https://www.anandtech.com/show/18805/amd-announces-alveo-ma35d-media-accelerator-av1-video-encode-at-1w-per-stream
