Intel’s Battlemage GPU strategy focuses on add-on features like dedicated matrix multiplication units and raytracing accelerators. Raytracing is becoming more prominent in games, as shown in a Cyberpunk 2077 frame on Intel’s Arc B580. The RTA’s BVH cache and improved shader array play key roles in boosting raytracing performance. The Port Royal benchmark showcases different raytracing effects, highlighting the need for a balance between BVH traversal hardware and vector execution units. While Cyberpunk 2077’s path tracing mode stresses shader array, Port Royal emphasizes RTA throughput. Intel’s focus on enhancing caches in Battlemage reflects the diverse demands of raytracing workloads. Looking ahead, Xe3 will introduce new features to further advance raytracing on discrete GPUs.
