Arm is announcing its new flagship Immortalis GPU today, its first to include hardware-based ray tracing on mobile. As PCs and the latest Xbox Series X and PS5 consoles are all gradually moving toward impressive ray-traced visuals, Immortalis-G715<\/a> is designed to be the Arm\u2019s first GPU to deliver the same on Android phones and tablets.<\/p>\n

Built on top of Mali, a GPU that\u2019s used by the likes of MediaTek and Samsung, Immortalis is designed with 10\u201316 cores in mind<\/a> and promises a boost of 15 percent over the previous generation premium Mali GPUs. Arm sees Immortalis as the start of a transition to ray tracing on mobile following its success with the 8 billion Mali GPUs that have shipped to date.<\/p>\n

\u201cThe challenge is that Ray Tracing techniques can use significant power, energy, and area across the mobile system-on-a-chip (SoC),\u201d explains Andy Craigen<\/a>, director of product management at Arm. \u201cHowever, Ray Tracing on Immortalis-G715 only uses 4 percent of the shader core area, while delivering more than 300 percent performance improvements through the hardware acceleration.\u201d It\u2019s not clear if a 3x speedup over software-based ray tracing will be enough to tempt game developers, but when Nvidia introduced hardware accelerated ray tracing in its RTX 2080, it advertised a 2x-3x boost<\/a> at the time. \u201cIt\u2019s the right performance point for now to get this technology into the market,\u201d says Arm\u2019s Paul Williamson, adding that it may also come in handy in augmented reality applications where RT could be used to match virtual lighting to the real-world environment around you.<\/p>\n

Arm is already delivering software-based ray tracing in last year\u2019s Mali-G710, but the promise of hardware support means we will start to see flagship smartphones with this chip at the beginning of 2023. Samsung also announced its Exynos 2200 chip<\/a> with hardware-based ray tracing earlier this year, so manufacturers are getting ready for the games to arrive.<\/p>\n

\u201cWe decided to introduce hardware-based Ray Tracing support now on Immortalis-G715 because our partners are ready, the hardware is ready, and the developer ecosystem is (about to get) ready,\u201d says Craigen. Arm is only providing a couple of examples of ray tracing on its mobile GPUs today, and there\u2019s no clear commitment from any game developers just yet. \u201cWe believe this technology has a strong place, but it\u2019ll take time,\u201d says Williamson, hinting that we should see \u201csome interesting experiences on mobile over the next year or so.\u201d<\/p>\n
