Project Amethyst: Sony and AMD's Official RDNA 5 Architecture for PS6

Project Amethyst is the official long-term collaboration between Sony and AMD for next-gen graphics and AI. {emphasis}

Unveiled October 2025 by Mark Cerny (Sony) and Jack Huynh (AMD), it forms the technical base for PS6’s GPU.

Three pillars of RDNA 5 for PS6

1. Radiance Cores - dedicated path tracing hardware.
2. Neural Arrays - matrix cores for PSSR AI upscaling and generative tasks.
3. Universal Compression - memory bandwidth compression to mitigate GDDR7 constraints.

These address BOM $960 pressures and enable 4K 60 FPS with path tracing. Unlike leaks, Amethyst is official, not rumor.

See PS6 specs, AI in PS6, PS6 Pro for tiering, and everything we know.
