Sony and AMD reveal Project Amethyst: Early look at PlayStation 6 technology

The conversation surrounding the next generation of console gaming has just received a significant boost from an authoritative source. Mark Cerny, the lead system architect behind both PlayStation 4 and PlayStation 5, has strongly hinted at the existence and timeline of the presumed PlayStation 6. In a new video released by PlayStation, Cerny and Jack Huynh, a Senior Vice President at AMD, unveiled Project Amethyst, a joint research initiative dedicated to machine learning-based technology for graphics and gameplay that will define the future of the platform.

While the discussion focused on technical breakthroughs, it was Cerny’s closing remarks that ignited speculation about the PS6’s potential launch window. “Overall, of course, it’s still very early days for these technologies,” Cerny noted. “They only exist in simulation right now, but the results are quite promising and I’m really excited about bringing them to a future console in a few years’ time.” This timeframe points to a likely release for the console around 2028, aligning with the traditional seven-to-eight-year console cycle.

A new era of visual efficiency for players

The core of Project Amethyst is the development of three major technological advancements: Neural Arrays, Radiance Cores, and Universal Compression. These features are designed to fundamentally change how game visuals are rendered, ultimately translating into a more immersive and smoother experience for the player.

The most exciting development for players looking for high fidelity and performance is the introduction of Neural Arrays. This feature tackles the resource-intensive nature of upscaling and denoising technologies, such as PSSR and FSR. According to Huynh, Neural Arrays allow compute units within the GPU to “team up, to actually share data and process things together like a single, focused AI engine.” Cerny added that this increased efficiency is a “game changer,” allowing the GPU to process a large portion of the screen in one go. For the player, this means next-generation upscaling will be significantly cleaner and run faster, delivering higher fidelity images without a major performance penalty.

Furthermore, the team introduced Radiance Cores, new dedicated hardware to manage complex lighting and shadow effects like real-time ray tracing and path tracing. By offloading these highly demanding calculations from the main shader units, Radiance Cores ensure that the GPU can focus on other critical tasks, promising a significant speed boost and enabling developers to implement more realistic and cinematic lighting in games. Finally, Universal Compression will dramatically reduce the memory bandwidth usage by efficiently compressing all data moving through the GPU. The goal of all these innovations working in concert is simple: to offer higher frame rates, more detailed assets, and a level of graphical realism that current-generation consoles cannot achieve.
