RADV Implements Triangle Pair Compression For AMD RDNA4 GPUs
The latest Radeon RADV driver ray-tracing optimization being merged to Mesa 25.3 is support for triangle pair compression with RDNA4 (GFX12) graphics processors.
The latest Radeon RADV driver ray-tracing optimization being merged to Mesa 25.3 is support for triangle pair compression with RDNA4 (GFX12) graphics processors. This compression technique groups adjacent triangles into pairs with the shared edges leading to better memory bandwidth efficiency and increased cache utilization. No performance numbers were shared as part of the Mesa merge request adding this triangle pair compression to Mesa RADV for Radeon RX 9000 "RDNA4" GPUs but every bit counts with Valve's relentless optimization work for this open-source Radeon Vulkan driver especially for ray-tracing where it has traditionally lagged behind but in recent months done a very fine job at becoming increasingly performant.
