Sony and AMD tease the GPU tech they’re constructing for the subsequent PlayStation

Sony simply dropped a brand new video with Mark Cerny, and it’s an enormous one, with important implications for the corporate’s subsequent console and AMD’s future GPUs. Over practically 9 minutes, Cerny, who was the lead designer for the PlayStation 4 and PS5, chats with Jack Huynh, senior vp and common supervisor of AMD’s Computing and Graphics Group, a few sequence of applied sciences, collectively dubbed Venture Amethyst, the 2 corporations are creating collectively. In line with Cerny, these applied sciences “solely exist in simulations” proper now, however they’re broadly designed to make the subsequent PlayStation higher at ray tracing, upscaling and different machine learning-based rendering strategies.

If you recognize something about AMD graphics playing cards, it’s that they’ve traditionally supplied poor ray tracing efficiency relative to NVIDIA’s RTX GPUs. For years, AMD tried to bridge the hole with playing cards that outmuscled NVIDIA’s choices with higher rasterization efficiency, an strategy the corporate now admits gained’t work for contemporary, graphically intensive video games. “Attempting to brute drive [ray-tracing] with uncooked energy alone simply doesn’t scale,” Huynh stated. AMD’s resolution is a wholly new structure that mixes two {hardware} improvements: Neural Arrays and Radiance Cores.

In AMD’s older GPUs, the person compute items are designed to work independently of each other. This strategy labored nice for a very long time, however in fashionable video games — dependent as they’re on costly upscaling strategies likes FSR and Sony’s own PSSR to ship playable framerates at excessive resolutions — it will probably result in inefficiencies. AMD is attempting to resolve that downside with Neural Arrays, which give the compute items a strategy to work collectively and share information between each other.

In line with Huynh, AMD isn’t linking a complete GPU collectively, as that will create a cable-management nightmare, however it’s giving the silicon a strategy to course of a “giant chunk” of the display in a single go. In observe, he says that ought to permit the subsequent PlayStation and AMD’s future video playing cards to supply a “entire new degree of machine studying efficiency.” In flip, that may translate to raised and sooner upscaling efficiency, alongside higher ray regeneration. The latter is one thing NVIDIA already gives with DLSS Ray Reconstruction and in video games that assist the expertise, it interprets to better-looking ray tracing results and improved efficiency.

As for Radiance Cores, it sound like AMD is taking one other web page from NVIDIA. For the uninitiated, the corporate’s RTX playing cards function devoted, fixed-function “RT” cores designed to speed up the mathematics wanted to simulate gentle rays in real-time. Huynh says the Radiance Cores are a wholly new {hardware} block designed to deal with ray and path tracing. “It’s a brand-new rendering strategy for AMD,” he added. As a bonus, by taking up this work, the Radiance Cores will unencumber different components of AMD’s new GPUs to course of shaders and textures extra rapidly, resulting in additional effectivity good points.

Lastly, the 2 corporations are engaged on new software program they’re calling Common Compression. It builds on the PS5 and PS5 Professional’s current Delta Coloration Compression approach. It’s going to theoretically permit Sony’s subsequent console to compress every thing that goes by its graphics pipeline, decreasing the quantity reminiscence bandwidth wanted by the GPU and probably decreasing its energy consumption.

Once more, I’ll observe Cerny stated it’s nonetheless “early days” for all of the applied sciences he and Huynh mentioned, nevertheless it’s reassuring to know Sony and AMD are fascinated by greatest strategy ray tracing efficiency and upscaling. Strategies like ray-traced international illumination can utterly change the look of a recreation, making for a extra immersive expertise. If Sony and AMD can discover methods to make these applied sciences inexpensive to run, that’s a win for everybody.
