Sony and AMD tease the GPU tech they're building for the next PlayStation

The article discusses the collaboration between Sony and AMD in developing new GPU technologies for the next PlayStation console. The key points are: 1. The two companies are working on a project called "Project Amethyst," which aims to improve the console's ray tracing, upscaling, and machine learning-based rendering capabilities. 2. AMD is developing a new GPU architecture that includes "Neural Arrays" and "Radiance Cores." Neural Arrays allow the compute units to work together and share data, improving machine learning performance. Radiance Cores are dedicated hardware for ray and path tracing, offloading this work from the main GPU. 3. The companies are also developing a new "Universal Compression" technique, building on the PS5's Delta Color Compression, to reduce the memory bandwidth and power consumption required by the GPU. 4. These technologies are still in the early stages of development, but they aim to address the shortcomings of AMD's previous GPUs in ray tracing performance, while also enhancing upscaling and rendering capabilities for the next PlayStation console.
