Radeon ROCm 3.10 Released With Data Center Tool Improvements, New APIs[2]

While we have been looking out for Radeon ROCm 4.0 that was announced back at SC20 as well as an updated ROCm for providing the RDNA2 compute support only found currently in their packaged RX 6800 series Linux driver, ROCm 3.10 arrived on Wednesday as an unexpected twist.

ROCm 4.0 has yet to debut via the usual channels. The ROCm 3.10 release also comes without any mentioned GFX10 RDNA/RDN2 support. We are waiting to hear back from AMD on when ROCm 4.0 is now expected for release.

Khronos Brings New Physically Based Rendering Materials Support To glTF[3]

The 's glTF specification that is a transmission format for 3D scenes and models continues picking up more impressive capabilities as its adoption by a growing range of software packages continue.

With companies from to Autodesk supporting glTF in various capacities for 3D models, the demands on this format continue to increase. Today the glTF working group at Khronos is introducing a set of new physically based rendering (PBR) extensions to offer new capabilities for glTF.

Mesa 21.0 Adds Radeon HEVC SAO Encode Support - Phoronix [4]

For the "Video Core Next 2" hardware like Navi as well as Renoir APUs, HEVC "sample adaptive offset" support has landed in Mesa 21.0.

VCN 2.0 initially came with Navi 1x and a feature now being exposed in the Mesa 21.0 Radeon video encode code is support for HEVC/H.265 sample adaptive offset, or SAO for short. As explained at IEEE.org, Sample Adaptive Offset for HEVC is a in-loop filtering technique to reduce sample distortion. From that published data, "it is reported that SAO achieves on average 3.5% BD-rate reduction and up to 23.5% BD-rate reduction with less than 1% encoding time increase and about 2.5% decoding time increase under common test conditions of HEVC reference software version 8.0."
