    H264/H265 Encode maximum speed for Radeon Pro Duo

    encoder

      Hi to AlI

      I use Nvidia GTX 1080 for many TV streams transcoding with ffmpeg to HEVC (H265). But the 8Gb of ram is to low. Each stream become 250Mb of GPU RAM.

      So I want to know ENCODE maximum speed for RADEON PRO DUO POLARIS 32GB for using of this card in streams transcoding.

      For Nvidia GTX 1080 with GP104 encode speed is - 2 stream of 4k video 60 Hz

      // In theory

      4k - 3840 x 2160 pixels, also encode speed can be calculated

      2 (stream) x 3840 x 2160 x 60 = 995328000 pixels / second

       

      so, for FullHD  - 995328000 / 1920 / 1080 / 25 Hz = 19 streams

       

      Can anybody ask me about Radeon Pro Duo encode speed parameters ?

      Thanks
