AMD Radeon: New standards and new capabilities

AMD Radeon Technology Group update

AMD Radeon Technology group have took place  in california. It is led by Raja Koduri (senior vice president and chief Architect). They have not disclosed about any of its new graphic architectures. But they have revealed about new video standards, Freesync capabilites. New Graphics cards in 2016 will also support for new HDR( High Dynamic Range) Monitors.

Need of new video standards

AMD’s current graphic card support for standards such as HDMI 1.4a or DP 1.2. If you want to play games on 4K resolution with 60 FPS, you will need a new standard. This data cannot rely on current video cards. So, there is a need for new standards as HDMI 2.0 or DP 1.3(DisplayPort 1.3). It will introduce a faster signaling mode for DisplayPort – High Bit Rate 3 (HBR3) – which in turn will allow DisplayPort 1.3 to offer 50% more bandwidth than the current DisplayPort 1.2 and HBR2. This will boost DisplayPort’s bandwidth to 32.4 Gbps before overhead. DisplayPort 1.3 also support for 4:4:4 display at 120 Hz.

FreeSync Capabiltites

with new AMD Crimson Software update, there is an update to AMD’s FreeSync technology. It is called as “Low Framerate Compensation”. Display port isn’t  popular in india, but every LED TV comes with HDMI port. Both G-Sync and FreeSync have been limited to DisplayPort 1.2 monitors.

The practical impact of LFC is less overall motion judder and a better image. But Nvidia has started supporting for HDMI 2.0 standard in their GPU from Nvidia 2014. Current generation AMD Radeon cards falls back due to the support for old video standards. I think AMD will bring the support for new video standards in their 14 nm GPU in “Arctic Islands” or “AMD Radeon Rx 400 series”.

The AMD Radeon Technologies Group is promising that their implementation will be fully compatible with future Radeon cards and confirms completely to the HDMI core standard. You can still use this display with an Intel or Nvidia GPU. In other words, you’ll be able to use it as a FreeSync display with future AMD Radeon cards.

HDR Video Summary

HDR is most traditionally defined with respect to the contrast ratio and the range of brightness within an image. for HDR video, there is a requirement of rendering a video in 10 bit per color. The Radeon 300 series is already capable of 10bpc rendering. Even older card will render the HDR content on a suitable monitor. More bit requires more bandwidth. Radeon 300 series cannot combine 4K + HDR + 60 Hz. So, 2016 Radeon GPUs with DisplayPort 1.3 would be able to support HDR at 4K@60Hz.

New update about this video standards from Radeon Technologies group will hopefully be available in CES 2016.
