In an old test i did about 18 months ago, i was able to get transcode the following using an Asrock A380 6GB using the "slow" preset, so you may get more if you use a faster preset.
10 concurrent streams from 2160p HDR H265 > 1080p SDR H264 (approx 46fps per stream)
16 concurrent streams from 2160p SDR H265 > 1080p SDR H264 (approx 30fps per stream)
Unfortunately i'm led to believe 10 is probably the max for 2160pHDR->SDR due to the ram/memory bandwidth on the card for tonemapping.
