Quick Sync on Alder Lake has hardware encoder support for HEVC 8, 10, and 12bit and decoder support for AV1.
Anecdotally, my busy Plex server (Alder Lake but not an N100) routinely ends up doing 3-4 concurrent transcodes, often involving high bitrate 4K HDR content. The Quick Sync encoders take almost all of the load off the CPU and never have trouble keeping up.
That said, I haven't had great experiences driving a display with 4K+ HDR content on an Alder Lake iGPU. At 60hz it's not too bad, but it can get stuttery past 100hz particularly in high contrast scenes with lots of movement.
