Video encoders of Radeon RX Vega M GH Graphics

A follow-up observation about encoders of Radeon RX Vega M GH Graphics of Hades Canyon NUC and the measurement app from the previous post:

The side by side comparison with desktop RX 570 card shows a few interesting things:

  1. Radeon RX Vega M GH Graphics has the latest driver, but AMF runtime version is way behind the latest: 1.4.11, that is, the system does not receive timely update (and overall its already discontinued)
  2. Even though some performance tuning might be coming from AMF updates, H.265/HEVC encoder performance suggests that the circuitry is pretty much the same and HEVC encoder numbers are close
  3. Embedded version of H.264 encoder is limited to nicely support 1920×1080@60 with reasonable headspace and it is assumed that higher resolutions are to be handled by next gen codec; yet desktop version received an improved version of H.264 encoder to cover real-time processing of 2560×1440@60 and 3820×2160@30
