About this tag
GPU research on WindowsForum.com covers graphics-architecture experiments and the practical limits of current Radeon hardware. A recurring example is AMD's tetrahedral-cage ray-tracing work, which demonstrated roughly 25,000 independently animated plants and about 500 million animated triangles at over 60 frames per second at 1080p on a Radeon RX 9070 XT. The notable finding was memory efficiency: bounding-volume-hierarchy storage dropped from as much as 80 GB to about 1.7 GB, while per-frame BVH update time fell from over 300 ms to roughly 3.3 ms. Discussion here tends to focus on how such research translates into real-time rendering on consumer GPUs.

    AMD Radeon RX 9070 XT Demo Cuts Ray-Tracing BVH Memory to 1.7GB

    AMD’s tetrahedral-cage ray-tracing research shows a way to make a workload that would be impossible on a Radeon RX 9070 XT’s ordinary VRAM budget fit into a real-time demonstration: about 25,000 independently animated plants, roughly 500 million animated triangles after level-of-detail...
