A new video with PS5 lead architect Mark Cerny and AMD SVP Jack Huynh has shed more light on the technology that could potentially power the yet-to-be-announced PlayStation 6 console. AMD and Sony have been collaborating through Project Amethyst, an initiative designed to push gaming technology forward, and Cerny added that he's really excited to bring recent breakthroughs to a "future console."Expect a "game-changer" in future upscaling technologiesAccording to Cerny and Huyn, there have been three big developments recently. Cerny explained that current technologies like FSR and PSSR are extremely demanding on GPUs and system memory. The first new concept revealed was Neural Arrays, which Hyung explained was designed to overcome inefficiencies encountered by subdividing neural network problems across many compute units. Neural Arrays allow compute units to "team up" and share data, and the end result here is that this can lead to better FSR and ray tracing effects, more efficiency, and better scalability as a workload grows."Neural Arrays will allow us to process a large chunk of the screen in one go, and the efficiencies that come from that are going to be a game-changer as we begin to develop the next generation of upscaling and denoising technologies together," Cerny explained.Cerny and Hyung also expect ray tracing to improve through the use of Neural Radiance Caching--which was unveiled at Computex earlier this year--and Radiance Cores. Together, ray tracing and path tracing can be handled together in real time, allowing developers to access a new level of realistic lighting while also allowing the CPU to focus on geometry and simulation tasks. "A cleaner, faster, and more efficient pipeline built for the next generation of ray-traced games," Huynh said.The other big reveal was Universal Compression, a new system designed for future GPUs and software-on-chips as a way to dramatically reduce memory bandwidth usage. This is an expansion of current technologies utilized on PS5 and PS5 Pro, and Universal Compression will evaluate and compress every piece of data on its way to the system memory. This will then lead to lower power consumption, higher visual quality, and improved performance."It's still very early days for these technologies, 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," Cerny concluded.This year will mark the fifth anniversary of the PS5's launch, but there have been a few hints from Sony regarding its plans for a successor console. One proposed idea is a detachable disc drive, giving the rumored console a layer of modularity. We also know that Sony will continue to rely on hardware over cloud technology, as it's aware that its users prefer the "local execution" of games that comes from a physical disc or having the software directly downloaded to the system.
