Nvidia Pascal GTX 1080 Is HDR-Ready, First to allow 4K Streaming via Microsoft’s PlayReady 3.0
Back in December last year, at an event in Sonoma, CA, AMD revealed some details about their Polaris’ display pipeline which was ready to support high dynamic range (HDR) content and display. Now, Nvidia is answering AMD’s HDR initiative with Pascal.
Nvidia’s next generation Pascal architecture features similar functionality, some of which was even already available in Maxwell; for instance, 12-bit color depth on GP104’s display controller, BT.2020 wide color gamut support, SMPTE 2084 electro-optical transfer function and HDMI 2.0b with HDCP 2.2.
Now, adding to that list are a number of interesting new features which are described as below.
Nvidia Pascal brings HEVC decoding at 4K @ 60hz and 10/12-bit color, which hints at support for HEVC version 2. This comes via fixed-function hardware, instead of the previous hybrid approach that leveraged software, and was limited to eight bits of color information per pixel.
The implementation is also part of Nvidia’s push to support the PlayReady 3.0 specification, making Pascal the first GPU to allow 4K streaming on PC via Microsoft’s standard.
The architecture also supports HEVC encoding at 4K @ 60hz in 10-bit color for HDR recording and streaming. Using this coupled with the GameStream HDR software, you would be able to stream HDR-enabled games to a Shield console attached to an HDR TV.
Additionally, the GTX 1080 is DisplayPort 1.3/1.4-ready, along with DP 1.2, which assists in the HDR Metadata Transport.
Nvidia GeForce GTX 1080 launches on May 27th, and should be available globally in both reference and non-reference flavors. Click here to check out GTX 1080’s full specs and features, including Async Compute, new SLI HB bridges, and many others.
