Overview

• In an official video, Mark Cerny and AMD’s Jack Huynh detailed three Project Amethyst initiatives: Neural Arrays, Radiance Cores, and Universal Compression.
• Neural Arrays are designed to let GPU compute units cooperate on larger screen regions to improve ML upscaling, denoising, and ray regeneration efficiency.
• Radiance Cores are proposed as dedicated hardware to handle ray and path tracing in real time, freeing CPUs for geometry and simulation and streamlining the rendering pipeline.
• Universal Compression would evaluate all GPU-bound data—not just textures—to reduce memory bandwidth demands, enabling higher detail, higher frame rates, and lower power use.
• The companies stressed these technologies exist only in simulation today, with Cerny saying they are intended for a future console in a few years; AMD also emphasized plans to bring the innovations to developers across platforms, and outlets report a PS5 Pro PSSR upgrade is slated for 2026.
