Unfortunately for RTG, theyre playing a bit of catch-up here, as the HDMI 2.0 standard is already more than 2 years old and has been supported by NVIDIA since the Maxwell 2 architecture in 2014. Though they didnt go into detail, I was told that AMD/RTGs plans for HDMI 2.0 support were impacted by the cancelation of the companys 20nm planar GPUs, and as a result HDMI 2.0 support was pushed back to the companys 2016 GPUs. The one bit of good news here for RTG is that HDMI 2.0 is still a bit of a mess not all HDMI 2.0 TVs actually support 4Kp60 with full chroma sampling (4:4:4) but that is quickly changing.
