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 is designed to be the Arm’s first GPU to deliver the same on Android phones and tablets.

Built on top of Mali, a GPU that’s used by the likes of MediaTek and Samsung, Immortalis is designed with 10–16 cores in mind 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.

“The challenge is that Ray Tracing techniques can use significant power, energy, and area across the mobile system-on-a-chip (SoC),” explains Andy Craigen, director of product management at Arm. “However, 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.” It’s 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 at the time. “It’s the right performance point for now to get this technology into the market,” says Arm’s 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.


Arm is already delivering software-based ray tracing in last year’s 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 with hardware-based ray tracing earlier this year, so manufacturers are getting ready for the games to arrive.

“We 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,” says Craigen. Arm is only providing a couple of examples of ray tracing on its mobile GPUs today, and there’s no clear commitment from any game developers just yet. “We believe this technology has a strong place, but it’ll take time,” says Williamson, hinting that we should see “some interesting experiences on mobile over the next year or so.”

Arm also has an update to its main Mali line with the Mali-G715. This GPU includes variable rate shading (VRS) to boost gaming performance and energy savings on mobile. VRS essentially renders the parts of a scene in a game that require more detail, so details in the background don’t need as much rendering power. “When enabling Variable Rate Shading on gaming content, we have seen improvements of up to 40 percent on frames per second,” claims Craigen. Other improvements mean these latest Arm GPUs will see a 15 percent energy efficiency improvement over its previous Mali-G710 GPU that was introduced last year. Arm wouldn’t say how much more expensive an Immortalis device might be compared to a Mali-based one.

Arm’s move to support hardware-based ray tracing on its GPUs is a significant step for mobile Android gaming. Ray tracing is currently limited to powerful GPUs that are typically found in gaming PCs or the latest Xbox Series X and PS5 consoles. Nvidia has previously demonstrated ray tracing in conjunction with Arm last year, but it was an RTX 3060 GPU paired with a MediaTek Kompanio 1200 Arm processor. That effort is focused on PCs and likely Chromebook-like laptops, but Arm’s new Immortalis is focused squarely on Android.

Arm also shared a chunk of its roadmap, which you can view above, suggesting it’ll follow up Immortalis with a flagship “Titan” GPU in 2023 and “Krake” in 2024. Arm declined to tell us if Titan or Krake will expand ray tracing support, though.

Epic Games is putting its support behind Immortalis with its Unreal Engine, alongside MediaTek and Unity. This is the type of industry support you’d expect for a new mobile GPU like this, but the real test will be how many mobile game developers start implementing ray tracing. (Arm says its ray tracing will use the Vulkan API.) It’s still incredibly rare to see ray tracing on console games, so it’s unlikely we’ll see a flood of mobile games moving to ray tracing anytime soon.

This time last year, I wrote about how digital experiences had never been more important, from personal to business devices - they helped us stay connected and entertained at a time when we needed it most. Compute continues to define our experiences in the modern world, and now these experiences are becoming even more visual.

Smartphones are at the center of our connected lives. From gaming to productivity, through video calling, social media or virtual environments, it is the device that provides us the connection to everyone and everything, in real time. For developers, making these immersive real-time 3D experiences even more compelling and engaging requires more performance. Arm sets the standard for performance and efficient compute, and our latest suite of compute solutions for consumer devices will continue to raise the threshold of what's possible in the mobile market, shaping the visual experiences of tomorrow.

Optimizing visual experiences with Arm Total Compute Solutions
Arm's Total Compute strategy has always been anchored in developer access, security and compute performance. We set out to deliver uncompromised performance leadership for all consumer device markets and we're constantly pushing the boundaries on what our partners can create with optimized system design and implementation.

Arm's 2022 Total Compute Solutions (TCS22) offer different levels of performance, efficiency and scalability, and bring together all elements of the Total Compute strategy. The combination of Arm IP launched in TCS22 will offer up to 28% more performance and up to 16% power reduction across a range of workloads, such as gaming, where benefits will include longer play time. We continue to expand the dimensions of performance beyond general-purpose workloads to workloads requiring specialized processing, propelling mobile technology, not just on the GPU but across CPUs and System IP too.
